[PATCH V4] xfstests: generic/314, test sgid inheritance on subdirs

[Carlos Maiolino <cmaiolino@xxxxxxxxxx>]

Tests if subdirectories created on the filesystem will properly inherit sgid bit
when this is set on the parent directory, once the process has the properly
permissions to create a subdirectory, this, should inherit parent's sgid bit if
this is set and irix_sgid_inherit sysctl is disabled.

V2: add missing source of "attr" file for _require_acls

V3: use _ls_l to filter out the selinux "."
    renumber to 314 to make the merge easier

V4: fix 314.out to the correct output

Thanks to Sandeen who have written this patch
