tests: Run the tests for the Python bindings of GPGME.

* tests/gpgme/gpgme-defs.scm (create-file): Write lines.
(create-gpgmehome): Extend function to create the right environment
for the Python tests.
* tests/gpgme/run-tests.scm: Make an environment cache for the Python
tests and enable them.
* tests/gpgme/wrap.scm: Do not hardcode the path of the Python
interpreter.
