tests: Make it possible to use pytest directlywip/creiter/pytest-direct

pytest will just import the files passed to it and try to run tests.
Since we need to run some setup code convert the tests directory to
a Python package and do the initialization in __init__.py. This makes
the init code (env vars, typelib search path, dbus) always run when
something from the package gets imported.

    python3 setup.py build_tests  # build pygobject and tests
    py.test-3 tests/test_gi.py  # run tests in test_gi.py only
