fedora: Handle upgrades from rhel package.

Currently we have rhel/openvswitch.spec.in that provides sysv scripts. The fedora package provides systemd scripts. If one upgrades openvswitch package from sysv to systemd, you will end up in a situation where old OVS daemons are running, but systemd does not know about it. One "restart" is needed for systemd to see the old daemons. Another "restart" or "force-reload-kmod" is needed to actually use the new daemons. This commit, just takes care of the first restart. The "real" restart/force-reload-kmod will still have to be done outside the package installation. Signed-off-by: Gurucharan Shetty <[email protected]> Acked-by: Ansis Atteka <[email protected]>
