LU-12267 tests: filter trailing '.' for SELinux

When SELinux is enforced, sanity test 420 fails due to
the "ls -n" command producing an extra '.' at the end of
the file/directory permissions to indicate extra security
attributes are set.

We need to filter out the trailing '.' in the 'ls -n'
output for testing to pass when SELinux is enabled.
