LU-12267 tests: update filter in acl for SElinux case

LU-12267 tests: update filter in acl for SElinux case

With SElinux enforced on client, sanity.sh test_103a fails because
the "ls -l" command produces an extra '.' at the end to indicate
extra security attributes are set.

So update filter by removing this trailing '.' in the output.
