Subject: [PATCH] tests: Remove strict dependency on testing package

It's bad practice to require internal testing/tests packages

in the main package. This results in all the clients of `numpy`

have parasitic dependencies on numpy-testing/tests and their deps.

This must be avoided in distro packaging.
