Further fixes for ssl_passphrase_callback test module.

The Makefile should set TAP_TESTS = 1, not implement the infrastructure
for itself.  For one thing, it missed the appropriate "make clean"
steps.  For another, the buildfarm isn't running this test because
it wasn't hooked into "make installcheck" either.
