package/python-m2r: remove package
Since the bump of python-mistune to version 2.0.4 in commit
ead539c27dd61ba010b3723b26af91da0779eb98, the python-m2r package fails
to build: it is no longer maintained and no longer compatible with
recent versions of python-mistune.
Since the only user of python-m2r, python-automat, no longer needs it,
we can safely drop this package.
