* guix/build/pyproject-build-system(check): Add python test-backend.

This will help in cases where a simple `python -m module args` call has
to be made instead of fully replacing the 'check phase, e.g. unittest
or django. This is never enabled unless #:test-backend 'python is set,
so it doesn't break anything.

As an example, the following snippet...

(arguments
  (list #:phases #~(modify-phases %standard-phases
                     (replace 'check
                       (lambda* (#:key tests? #:allow-other-keys)
                         (when tests?
                           (invoke "python" "-m" "unittest"
                                   "diff_match_patch.tests")))))))

...can be transformed like this: 

(arguments
  '(#:test-backend 'python
    #:test-flags (list "-m" "unittest" "diff_match_patch.tests")))
