This has been itching me, and actually it proves to not be that
complicated to achieve per the attached.  This makes all the tests from
contrib/ and src/test/modules pass with temporary installations, the
tests runs are much slower though.  This would not blow up the buildfarm
visibly, buts its code assumes that installcheck should be used, so we
could as well just introduce new options for vcregress.pl.  I am not
sure what would be the best way, still using temporary installations has
the merit to not cause any tests to run unconfigured in the future.
