rhel/systemd: Change owner recursively and also on /etc/openvswitch.

Since we use a floating user (user with dynamic userid) and floating
groups (groups with dynamic groupid), when you use bootc the uid/gid of
the directory may change and so it's necessary to be sure that the
uid/gid is updated each time you try to start the daemon.

ovsdb-server.service is the correct place to do that, since
ovs-vswitchd.service uses After=ovsdb-server.service and so it's always started
after it.

See bootc-dev/bootc#673 (comment)
