Allow vcregress.pl to run an arbitrary TAP test set

Currently only provision for running the bin checks in a single step is
provided for. Now these tests can be run individually, as well as tests
in other locations (e.g. src.test/recover).

Also provide for suppressing unnecessary temp installs by setting the
NO_TEMP_INSTALL environment variable just as the Makefiles do.

Backpatch to 9.4.
