[PATCH 2/4] selinux-testsuite: allow the file test to work with all coreutils versions

[Paul Moore <pmoore@redhat.com>]

Prior to coreutils v8.23 the 'ls -Z' output looked like the following:

  # /bin/ls -Z test
  -rw-r--r--. root root unconfined_u:object_r:user_tmp_t:s0 test

However, with the coreutils v8.23 release the output changed to:

  # /bin/ls -Z test
  system_u:object_r:test_file_t:s0 test

This patch attempts to detect the version of /bin/ls in use and adjusts
accordingly.
