The purelib and platlib were both defined to /usr/lib64/python on
64bits systems. This is because:
>>> get_python_lib(standard_lib=1, plat_specific=0)
'/usr/lib64/python3.7'
>>> get_python_lib(standard_lib=1, plat_specific=1)
'/usr/lib64/python3.7'
>>> get_python_lib(standard_lib=0, plat_specific=0)
'/usr/lib/python3.7/site-packages'
>>> get_python_lib(standard_lib=0, plat_specific=1)
'/usr/lib64/python3.7/site-packages'
So now we use standard_lib=0 to get the site-packages base path
from /usr/lib and not /usr/lib64.

This package is not being kept up to date, it's hard to maintain and we
will need to tune it from time to time which is painful.
Also removes whole layer of bootstrapping.
