Allow building the python module with system zlib
When building the python module and using the new
GRPC_PYTHON_BUILD_SYSTEM_ZLIB env variable, the third party zlib code
is not compiled. Instead, the zlib shared library installed on the
system is used during runtime.
This is useful for distributions who don't want to include code copies
but use shared libraries instead.
