Revert "Replace use of deprecated Python module distutils.sysconfig"

Browse Source 
This reverts commit e0e567a106726f6709601ee7cffe73eb6da8084e.

On various platforms, the new approach using the sysconfig module
reported incorrect values for the include directory, and so any
Python-related compilations failed.  Revert for now and revisit later.
