Skip some proced-tests that appear to be hanging

Skip the same proced-tests that are now skipped upstream because they
were hanging on darwin, since proced-tests has been intermittently been
hanging on Debian too.  Just change the skip-when criteria in the
upstream commit from 'darwin to t.

Also skip the two tests that were already being skipped on darwin, since
proced-tests was still hanging with those enabled in Debian.

 They were hanging on the buildds and locally, so as with darwin
 upstream, we now skip them too.
