python: Get version information from the build system.

* configure.ac: Generate 'setup.py' and 'version.py'.
* lang/python/Makefile.am: Use generated setup script.
* lang/python/pyme/version.py: Turn it into a template, and get
version information from the build system.  Also drop some variables.
* lang/python/setup.py: Likewise.  This way we can avoid importing the
version module, which is frowned upon and actually caused a problem.
