python-utils-r1.eclass: Enable hardlinking of identical pyc files for py3.9+

Browse Source 
Python 3.9 includes a new feature for compileall to automatically hardlink
different optimization level cache files if they are identical. Make use of it
for python_optimize for some space savings.
This however does not cover distutils use cases and python itself.
