what we need is "libnl-genl-3-dev", libnl-3-dev should be a dependency
of "libnl-genl-3-dev". the only reason we would have added it, is if
the package maintainer of "libnl-genl-3-dev" fails to do so. and
the packages of "libnl-genl-3-dev" on both debian and ubuntu just look
correct in this perspective.
so let's remove this.
