redhat: Create /etc/openvswitch/* with openvswitch as user/group

Without this commit is not possible to upgrade an openvswitch release
that includes the commit ac416a3 (for example 2.8.0) with another release
that includes the commit ac416a3 (for example master or 2.8.1), because
rpm changes the user/group of /etc/openvswitch to root/root, but ovsdb-server
starts with the user openvswitch and so it doesn't have permissions to write in
/etc/openvswitch/conf.db.

This patch tell rpm to use the openvswitch user and group for
/etc/openvswitch and /etc/openvswitch/default.conf.
