debian: clean with "--component remotefilelog" to not need Cython

I was trying to build a Debian package on a build machine without
Cython installed. That failed when it was running "dh clean --with
python2", which calls the dh_auto_clean target, which in turn calls
"python setup.py clean --all". Overriding that target to pass
"--component remotefilelog" seems to solve the problem.

The internet wasn't able to tell me what else is supposed to be done
in dh_auto_clean, so I can only hope that nothing else than "python
setup.py clean --all" was supposed to be done there.
