* we need new enough for cmake 3
* but not so new it depends on libubox
This is a "get it working again" patch, not a long-term solution.
Either we should add libubox to liminix or we should find another
dhcp6 client
* [] is now [ ]
* {} is now { }
* commas in arglists go at end of line not beginning
In short, I ran the whole thing through nixfmt-rfc-style but only
accepted about 30% of its changes. I might grow accustomed to more
of it over time
