Correctly substitute directory names in 'python' executable.

Previously "@libdir@" would typically expand to "${exec_prefix}/…",
which wouldn't have the intended effect.

* modules/Makefile.am (python): New target.
(CLEANFILES): New variable.
* modules/configure.ac: Remove 'AC_CONFIG_FILES' for 'python'.
* modules/python.in: Use @datadir@ instead of @prefix@/share.
