Test coverage with multiprocessing fix

The test coverage of avocado gathered by coverage.py. It was not precise, because some of our functional tests were running in sub-processes where the coverage was not enabled. This change it adds `sitecustomize.py` to ensure that coverage will be enabled for all python processes which will run during coverage testing. After this change, the overall test coverage of avocado will increase from 54% to 68% Reference: https://coverage.readthedocs.io/en/latest/subprocess.html Signed-off-by: Jan Richter <[email protected]>
