Update EB hooks - raise error when use_pip is not used

[ccoulombe]

To accompany https://github.com/ComputeCanada/software-stack/issues/137, and prevent future oopsies, we need to raise an error if a module has a Python extension and uses python setup.py install and not pip install.

We then need to update the recipe to use:

        'use_pip': True,
        'use_pip_for_deps': True,
        'sanity_pip_check': True,

and fix/update any issues with the installed python packages.

I suggest setting

exts_default_options['use_pip'] = True
exts_default_options['use_pip_for_deps'] = True
exts_default_options['sanity_pip_check'] = True

if there are Python extensions

Or maybe add a sanity check that there are no .egg files in the install dir ?

Testing for use_pip in all extensions is not trivial.

I'd prefer to raise an error (like we do with CMake). Plus, these will be defaults in the next EB version

Plus, these will be defaults in the next EB version

which won't raise an error
