Add checkbox for running test in GH build workflow (#4246)

Currently when we run a build with limited set of boards that doesn't include
OVA, the test job fails because the OVA artifact is missing. Add a checkbox for
running tests and ensure that OVA artifact is built if it's enabled.

(cherry picked from commit 71d222ad91)
