Show an error message when the python_requires classifier of the package gets ignored, so that users can't accidentally install an incompatible version of Streamlink with their unsupported Python version / environment. Also bump the required version of pip to >=9 in dev-requirements.

I've seen this too many times now. We should add a check to setup.py which prevents installs of Streamlink in incompatible python environments when the python_requires package classifier gets ignored (eg. on older pip versions).

I would also prefer having a clean
setup.cfgwith declarative package information instead of having package information defined programmatically insetup.py. That's a different issue though. Also a bit confusing for me since I don't know much of the history of python package management. It's pretty messy and everyone's doing their own thing (which the community is trying to change from what it looks like).https://setuptools.pypa.io/en/latest/userguide/declarative_config.html
