Johnothan King bd9faa81bf libast: Use POSIX_SPAWN_SETSID in spawnveg when needed (#439) 
This commit implements support for POSIX_SPAWN_SETSID in
spawnveg(3). The fork/vfork fallback for spawnveg already attempts
to use setsid in the manner described by the man page, so the
posix_spawn implementation should also do so.

src/lib/libast/comp/spawnveg.c:
- Add support for POSIX_SPAWN_SETSID to the posix_spawn version of
  spawnveg.
- Minor extra: Remove dead code that's never used (the
  _lib_posix_spawn < 2 code block is inside of _lib_posix_spawn >
  1, plus when it's manually enabled by changing the previous #if
  condition you'll find it causes many regression test failures (at
  least on OpenBSD)).

src/lib/libast/man/spawnveg.3:
- Document that spawnveg cannot make the new process a session
  leader if the operating system doesn't support POSIX_SPAWN_SETSID
  and the new process was created using posix_spawn.
