Simplify spec file a little bit

The plugin for cifs-utils can be built on all supported versions of fedora.
Conditions are required only in upstream spec file for older
distributions. Definition of constant with_cifs_utils_plugin is still
in the beginning of spec file for simpler comparison of changes
between upstream and fedora.

(cherry picked from commit 5ce8ae1166)
