Merge bctest.py into bitcoin-util-test.py

bctest.py is only used as an import by bitcoin-util-test.py. There's no
value in keeping it as a separate module, so let's merge them into a
single module to keep building and packaging simpler.

bitcoin-test-util is importable as a module, so if any future modules
really want to import the code from bctest.py, they can import
bitcoin-test-util and call the bctest functions by name.
