[PATCH] generic/004: Check resulting file permissions

[Andreas Gruenbacher <agruenba@redhat.com>]

Check the file permissions resulting from linking an O_TMPFILE file into
the namespace: they should be the same as creating a normal file.

(Note that this patch depends on patch "xfs_io: Fix initial -m option"
for xfsprogs.)
