[update][queens] layered openvswitch workaround is broken.

Hi,

originally reported there https://bugzilla.redhat.com/show_bug.cgi?id=1883786

Basically, we introduced a regression, that make the layer product upgrade workaround for ovs non effective.

Luckily the openvswitch workaround kicks in in all the testing we've done, so we don't get any issue, but the issue should be fixed nevertheless.

Example of what happens:

2020-09-29 14:08:00 | TASK [Get current OpenvSwitch package name] ************************************
2020-09-29 14:08:00 | Tuesday 29 September 2020 13:52:26 -0400 (0:00:00.503) 0:05:27.767 *****

2020-09-29 14:08:00 | changed: [controller-2] => {"changed": true, "cmd": "rpm -qa | awk -F- '/^(openvswitch[0-9]+\\.[0-9]+-[0-9]+\\.[0-9]+\\.[-0]+-|openvswitch-2)/{print $1}'", "delta": "0:00:01.258453", "end": "2020-09-29 17:52:27.655876", "rc": 0, "start": "2020-09-29 17:52:26.397423", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []}

We can see that the regex matched nothing.

Basically the regex work with:

openvswitch2.11-2.11.0-35.el7fdp.x86_64

but fails with:

openvswitch2.11-2.11.3-64.el7fdp.x86_64
