Replace imp package in runtests.py

We get the following Deprecation when running tests.

runtests.py:1: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
  import imp

Make this go away. Also, figure out how to not search through the .git directories for tests.

You can import importlib (instead of imp), and try this patch:

- modules.append(imp.load_module(module_name, *imp.find_module(module_name)))
+ modules.append(importlib.import_module(module_name))

But as far as I can tell, it breaks the build on Python 2.7 and slows down tests on Python 3.7. I think I’ll put this issue on hold.

Can't figure out a solution that works well on Python 2 and 3. @{557058:9524f6a0-ef9f-4466-b913-d04e51ff9093} suggests a simpler loop over files, which is fine. But this isn't worth any more time than I already put into it.
