[new] net/arti

Arti is an implementation of Tor anonymity protocols, written in Rust.

It is intended to replace the C implementation at some point. It's
still missing features like bridges, transports and onion services, but
it's usable for regular connections. Here's the release announcement
for version 1.0.0: https://blog.torproject.org/arti_100_released/

Not sure if we want to add a dedicated user and rc.d script yet.
