Perform the environment modifications specific to DISTUTILS_EXT
to python_compile and python_test phases. These are the only phases
where we expect extension builds to be called. This allows us to
limit the scope of localized CPPFLAGS, as we both want to avoid leaking
changes to non-Python parts of the build and let ebuilds to manipulate
flags at their leisure, particularly prior to python_compile.
