gnu: Add missing imports for python-check....This fixes an issue introduced in 3bf5a19609560c7ba985eda66019eda15aaf4a86,
which caused `guix pull', `guix time-machine', and a few other commands to
fail.
* gnu/packages/diffoscope.scm: Import python-check.
* gnu/packages/django.scm: Likewise.
* gnu/packages/logging.scm: Likewise.
* gnu/packages/magic-wormhole.scm: Likewise.
