Put files from installed tests into a separate package to avoid having
them in an image unwanted and to avoid having more runtime
dependencies than necessary.
Background:
As setuptools is pretty much unregulated in terms what is installed
by some module, even tests are installed into base package, which then
go right into production, although completely unnecessary.
When now trying to determine the needed runtime dependencies, more
than actually needed will slip into the image.
To give a really bad example GitPython ships its tests into production
leading to the effect that theoretically besides the known RDEPENDS
python3-asyncio, python3-distutils, python3-idle, python3-misc,
python3-pickle, python3-shell, python3-ddt and python3-nose would be
required.
That's why I came up with the idea to package tests (if existing) into
a separate package, which is NOT installed by default.
Please let me know if you see any issues with that patch
