[yocto] [patchtest][PATCH 2/2] patchtest: Allow tests to import helper modules

[Paul Barker]

When running patchtest locally to figure out what was wrong with my
patch, I saw the similar exceptions for each test module:

    Traceback (most recent call last):
      File "/usr/lib/python3.6/unittest/case.py", line 59, in testPartExecutor
        yield
      File "/usr/lib/python3.6/unittest/case.py", line 605, in run
        testMethod()
      File "/usr/lib/python3.6/unittest/loader.py", line 34, in testFailure
        raise self._exception
    ImportError: Failed to import test module: tests.test_python_pylint
    Traceback (most recent call last):
      File "/usr/lib/python3.6/unittest/loader.py", line 428, in _find_test_path
        module = self._get_module_from_name(name)
      File "/usr/lib/python3.6/unittest/loader.py", line 369, in _get_module_from_name
        __import__(name)
      File "/mnt/build/Projects/Konsulko/patchtest/patchtest-oe/tests/test_python_pylint.py", line 18, in <module>
        import base
    ModuleNotFoundError: No module named 'base'

To fix this the import patch used when loading test modules has been
extended.
