James Hilliard fc429c4dc6 package/pkg-python: clean conflicting pep517 packages before install
The python installer package isn't able to overwrite files of packges
that already exist, this causes problems when doing a rebuild or
update without a full clean.

To fix this we can use functionality from importlib to identify and
remove any conflicting python package files before installation.

We also need to use internals from python-installer, as we want to use
the same logic as pyinstaller uses internally for getting the scheme so
that we ensure we clean the correct package scheme (we want it to be the
same as the one we're installing)

Fixes:
