Fixed logicalfile tests.

- file name is in coulmn 10 of 'ls -Z'
- selinux label is in column 5
- do not list '..' and '.'
- skip any 'total BLOCKS' in the first line of ls -lAZ output, rawhide puts it
  there, while Fedora 21 not.
Don't install the metacommand during tests.

It's already installed (or at least should be), all other tests work this way.
