Since on CentOS/RHEL the builds are based on stable branches and not on tags for debugging purpose it's better to have the downstream version as version so it's easier to know which commits are included in a build. This commit adds --with-version-suffix as ./configure option in order to set an OVS version suffix that should be shown to the user via ovs-vsctl -V and, so, also on database, on ovs-vsctl show and the other utilities. --with-version-suffix is used in Fedora/CentOS/RHEL spec file in order to have the version be aligned with the downstream one.
