[PATCH 0/2] test-lib: improve missing prereq handling

The ssh signing feature was breaking tests when the broken openssh-8.7
was used. We have now fixed that by checking for this exact case in the
GPGSSH prereq and I will improve that check further in a future patch.
However we are now in a situation where a broken openssh in the future
will result in successfull tests but not a working git build afterwards
(either not compiling in the expected feature or like in the ssh case
runtime failures) resulting in a false sense of security in the tests.
This patches try to improve this situation by showing which prereqs
failed in the test summary and by adding an environment variable to
enforce certain prereqs to succeed or abort the test otherwise.
