Use same interpreter for test-module and module it runs

Default python interpreter to the same interpreter the test-module
script is executed with.  This is so that the interpreter doesn't have
to be specified twice in the command when using non-default python
(e.g. ``/path/to/python ./hacking/test-module -I python=/path/to/python ...``)
