network: remove firewalld version check from networkSetBridgeZone()

Browse Source 
At the time the version check in this function was written, there were
still several supported versions of some distros that were using a
version of firewalld too old to support the "rich rule priorities"
used by the 'libvirt' zone that we installed for firewalld. Today the
newest distro that has a version of firewalld < 0.7.0 is
RHEL7/CentOS7, so we can remove the complexity and if the libvirt zone
is missing simply say "the libvirt zone is missing".
