upgrade: properly filter action depending on planned work
The `determineactions` function filters out deficiency that are not scheduled to
be fixed by the target repository configuration. However it only did so for
requirement we currently support, letting other actions for unsupported
requirement through even if the target repo configuration did not request it.
As a result the output of the command was easily polluted by experimental
feature with no upgrade support.
We rework the code to still filter out requirement based action without the
faulty filtering.
