fanctl, fan module: remove

This has been broken nearly all the time due to the patches needed to
iproute2 not being compatible with the newer versions we have been
shipping. As long as Ubuntu does not manage to upstream these changes
so they are maintained with iproute2 and we don't have a maintainer
updating these patches to new iproute2 versions it is not feasible to
have this available.
