add .debs to gettor
Lately we've had a number of Ubuntu users in countries that censor torproject.org trying to download the Debian packages from our Debian/Ubuntu repository and failing to do so because of the aforementioned blocking. We should add the .debs to gettor.
This appears to mostly be a consequence of us not having Tor in the Ubuntu repositories, because we don't see it with Debian and rpm-based distro users, so an alternative is to get it back in, but that is also fraught with complications.
