Use the tarball with all Tor Browser langpacks

Originally created by @intrigeri on #17400 (Redmine)

Adjust config/chroot_local-hooks/10-tbb to only download the en-US tarball + this new one
~~Update wiki/src/contribute/release_process/tor-browser.mdwn accordingly~~
~~Verify if we have anything else that needs to be aware of this new tarball (apt-cacher-ng config springs to mind)~~

This will make life easier for RMs and developers with poor Internet connections, and will save storage space on our servers.
