Previously when using --via-mpy, the file was compiled to tests/<tmp>.mpy
and then run using `micropython -m <tmp>` in the current cwd
(usually tests/). This meant that an import in the test would be resolved
relative to tests/.
This is different to regular (non-via-mpy) tests, where we run (for
example) `micropython basics/test.py` which means that an import would be
resolved relative to basics/.
Now --via-mpy matches the .py behavior. This is important because:
a) It makes it so import tests do the right thing.
b) There are directory names in tests/ that match built-in module names.
Furthermore, it always ensures the cwd (for both micropython and cpython)
is the test directory (e.g. basics/) rather than being left unset. This
also makes it clearer inside the test that e.g. file access is relative to
the Python file.
Updated tests with file paths to match.
