The long v3 .onion URL was causing havoc on small mobile
displays, so extract "hostname" into a variable which can
still used as a Bourne shell snippet.
While we're at it, include "torsocks" in the git command used
for .onion URLs since that's the (near)-universal wrapper for
Tor-ifying things (like git) which are dynamically linked to
libc.
