Correctly match openvswitch package

The current regex will match more than one package if the
openvswitchX.YZ-test package is installed.

eg:
rpm -qa | awk -F- '/^(openvswitch[0-9]+\.[0-9]+-|openvswitch-2)/'
openvswitch2.11-test-2.11.0-35.el7fdp.noarch
openvswitch2.11-2.11.0-35.el7fdp.x86_64

The right package to find has the form: openvswitchA.BC-A.BC.D-

So we change the regex to only match if it has that form.
