Require Python for PETSc

Browse Source 
PETSc requires Python for building.

I have a case where an HPC system has a very old default Python version, too old for Spack. So I load a module for Python, which makes Spack work. This module relies on LD_LIBRARY_PATH.

When building PETSc, Spack unsets LD_LIBRARY_PATH, breaking the Python that PETSc finds.

Explicitly requiring Python for PETSc makes building PETSc work.
