This hunk is a fix to the existing tst_get_free_gid_() success path --
removing | TERRNO so errno is not printed when a free GID is found.

That is a reasonable fix on its own, but it has no relationship to the
new tst_get_free_uid() API that the commit message describes. The commit
message does not mention it.

Could these be split into two patches?

  1/3  lib/tst_uid: Remove spurious TERRNO from tst_get_free_gid success path
  2/3  lib: New library function tst_get_free_uid
  3/3  open16: allow restricted O_CREAT of FIFOs and regular files

Verdict - Needs revision
