tests: avoid false failures on AIX

Browse Source 
* tests/ln/sf-1.sh: Limit the symlink size to 1MiB
to avoid memory exhaustion seen on NFS on AIX, giving:
  + printf '%0*d' 4294967296 0
  + ./tests/ln/sf-1.sh: line 38: printf: warning: 0: Result too large
* tests/id/setgid.sh: Skip the test when the adjusted gid
would equal 4294967295, as that's reserved on AIX.
