[PATCH] generic: Check linking O_TMPFILE into namespace with POSIX ACLs

[Andreas Gruenbacher <agruenba@redhat.com>]

When an O_TMPFILE file is linked into a directory with a POSIX default
ACL, the file should inherit the default ACL and the umask needs to be
ignored.

This goes together with generic/004, which tests O_TMPFILE files without
POSIX ACLs.
