python: Remove Python bindings

* README: Update.
* configure.ac: Remove checks, variables and file generations related to
the Python bindings. Remove python from available_languages and
default_languages.
* lang/Makefile.am (DIST_SUBDIRS): Remove python.
* lang/python: Remove.
* m4/ax_pkg_swig.m4, m4/ax_python_devel.m4, m4/python.m4: Remove.

The Python bindings have been moved to a separate Git repository:
gpgmepy.
