libnbcompat: Update to 20251029

This is the result of porting libnbcompat to Sortix, a hobby operating
system. Sortix is a relatively clean "legacy-free" POSIX implementation,
so the port revealed lots of historical Unix warts and BSDisms in
libnbcompat. These included:

- gratuitous use of <sys/param.h>, which is probably mostly unnecessary
  and cargo-culted (but libnbcompat is supposed to implement the header
  anyway, so use its internal copy)
- BSDisms: frequent use of u_int, u_long, caddr_t types
- other portability problems: for some reason, only defining MAXPATHLEN
  if missing on SCO

Verified to compile on a whole heap of platforms, see README for gory
details...

Log message:
libnbcompat: illumos does not have chflags() either.

Fixes GCC 14 build.

libnbcompat: Convert to a proper package.

Building this inline meant an excessive number of copies were built
during bootstrap, one for every package that required it.  Now only
one package is built, significantly reducing bootstrap time.
