openvswitch: enable systemd support
openvswitch: enable systemd support

Make the necessary updates to get openvswitch to be compatible with
systemd. Up to now if you built a systemd supported image openvswitch
was using the systemd sysvinit wrappers, by making these changes we
now support systemd natively.

Note that there is no equivalent systemd support for
openvswitch-testcontroller. Following the lead of upstream this
is not something that should be run by the init system.
