update dropbear patch for 26.05

CONFIG_RANDOMIZE_BASE enables KASLR. It doesn't increase the size of the
kernel image for OpenWrt One (technically it increases .text size by 256
bytes, but that was cancelled out by alignment padding). Set this to y on
arm64. The other architectures are not modified (arm doesn't support it,
and mips only supports it for some targets).

CONFIG_ARM64_PTR_AUTH is enabled by default by the kernel and enables
pointer authentication instructions at entry and exit of most kernel
functions. However, none of our targets support pointer authentication,
so these instructions are just taking up space for no purpose. Set this
one to n, which reduces OpenWrt One kernel image size by 24KB.

 ## Current status (does it work yet?)
 
-Liminix is pre-1.0. We are still finding new and better ways to do things,
-and there is no attempt to maintain backward compatibility with the old
-ways.
+Liminix 1.0 was released in April 2025. It works for me and I would
+say it has seen lots of use in the particular applications of "home
+wifi router" and "wireless extender".
+
+It's not “finished” - we are still finding new and better ways to do
+things - but we endeavour to signal future breaking changes through the
+version number. This is “semver-adjacent”, in that minor bumps
+(1.1, 1.2 …) are used for minor new features and major bumps (2.0 …)
+for changes that are likely to break out-of-tree modules or
+configurations. It won’t be semver exactly because [every change
+breaks someone’s workflow](https://xkcd.com/1172/), but we aspire to
+have the magnitude of the version delta correlate with the scale of
+the consequences of upgrading.
 
 The [NEWS](NEWS) file (available wherever you found this README) is
 a high-level overview of breaking changes.
 
 Development mostly happens on the `main` branch, which is therefore
 not guaranteed to build or to work on every commit. For the latest
-functioning version, see [the CI system](https://build.liminix.org/jobset/liminix/build) and pick a revision with all jobs green.

     The GL-AR750 "Creta" travel router features:
 
-     - QCA9531 @650Mhz SoC
-     - dual band wireless: IEEE 802.11a/b/g/n/ac
-     - two 10/100Mbps LAN ports and one WAN
-     - 128MB DDR2 RAM
-     - 16MB NOR Flash
-     - supported in OpenWrt by the "ath79" SoC family

-    The GL-AR750 has two distinct sets of wifi hardware. The 2.4GHz
-    radio is part of the QCA9531 SoC, i.e. it's on the same silicon as
-    the CPU, the Ethernet, the USB etc. The device is connected to the
-    host via `AHB <https://en.wikipedia.org/wiki/Advanced_Microcontroller_Bus_Architecture>`_ and it is
-    supported in Linux using the ath9k driver. 5GHz wifi
-    is provided by a QCA9887 PCIe (PCI embedded) WLAN chip,
-    supported by the ath10k driver.

     This is a 32 bit ARMv7 MVEBU device, which is usually shipped with
-    TurrisOS, an OpenWrt-based system. Rather than reformatting the
-    builtin storage, we install Liminix on to the existing btrfs

-    The install process has two stages, and is intended that you
-    should not need to open the device and add a serial console
-    (although it may be handy for visibility, and in case anything
-    goes wrong). First we build a minimal installation/recovery
-    system, then we reboot into that recovery image to prepare the
