Fixes setup_cantera and the post-install message to reference the path of the Python module on the target system rather than the staging directory. Also, generated .pyc files no long specify the path in the staging directory. This has no effect on the use of the .pyc files, but helps avoid warnings/errors from packaging system linters (notably, on FreeBSD). Fixes #1094
