gha: build-kata-static-tarball: Only push to registry after merge

56331bd7bc oversaw the fact that we
mistakenly tried to push the build containers to the registry for a PR,
rather than doing so only when the code is merged.

As the workflow is now shared between different actions, let's introduce
an input variable to specify which are the cases we actually need to
perform a push to the registry.

Fixes: #6592
