Make bsd.test.mk the only public mk fragment for the building of tests.

Change {atf,plain,tap}.test.mk to be internal implementation details of
bsd.test.mk.  Makefiles that build tests should now only include bsd.test.mk
and declaratively specify what they want to build, without worrying about
the internal implementation of the mk files.

The reason for this change is to permit building test programs of different
interfaces from a single directory, which is something I had a need for
while porting tests over from src/tools/regression/.

Additionally, this change makes it possible to perform some other requested
changes to bsd.test.mk in an easier manner.  Coming soon.
