The good news: the attached patch makes 'check' work as expected. The
bad news is that we have some breakages.

'python-py' fails with:

TypeError: py.test.__dict__ is not a dictionary

Which seems similar to

https://github.com/NixOS/nixpkgs/issues/12565#issuecomment-174165144

I tried adding a newer setuptools as input, to no avail. Needs more
investigation.

Subject: [PATCH] build-system/python: Make sure 'check' returns failures.

* guix/build/python-build-system.scm (check): Wrap 'call-setuppy' in 'if' so
that it actually fails when the tests fail. Print informational message when
skipped.
