Improve vcregress.pl's handling of tap tests for client programs

The target is now named 'bincheck' rather than 'tapcheck' so that it
reflects what is checked instead of the test mechanism. Some of the
logic is improved, making it easier to add further sets of TAP based
tests in future. Also, the environment setting logic is imrpoved.

As discussed on -hackers a couple of months ago.
