Switch to reprepro for generating local apt repositories

We don't install dpkg-dev in tools trees anymore to avoid pulling
in perl, which means we don't have access to dpkg-scanpackages in
tools trees anymore.

Instead of adding back dpkg-dev, let's instead switch to reprepro
for generating our local apt repository. It's written in C, packaged
everywhere and has hardly any dependencies.
