acl: improve Tru64 support

[Bruno Haible]

Hi Jim,

On Tru64, when TMPDIR is set to /tmp, the 3 tests pass. However, when TMPDIR
is set to an NFS-mounted directory, the tests fail:

setacl: tmpfile0: can't set acl: Operation not supported on socket
PASS: test-file-has-acl.sh
/home/haible/testdir0/build/gltests/test-set-mode-acl: setting permissions for 
`tmpfile1': Operation not supported on socket
mode = 700: tmpfile1 has wrong mode: -rw-------
FAIL: test-set-mode-acl.sh
/home/haible/testdir0/build/gltests/test-copy-acl: preserving permissions for 
`tmpfile1': Operation not supported on socket
FAIL: test-copy-acl.sh

This fixes it. OK to apply?
