[Tests] use absolute imports and add __init__.py where relevant

We can't use relative imports any more since the tests are now located outside the package.

I had to add __init__.py to Tests/feaLib/ so that pytest does not get confused by the presence
of two test files with the same basename: i.e. Tests/feaLib/builder_test.py and Tests/feaLib/builder_test.py
