I think it's a worthwhile change.  It'd be neat to unify every reference
to /var/run to /run in the doc/code too.

I'll be trying this on the build farm as there's an annoying problem
with anonip that creates FIFOs under /run/anonip, and these currently
become plain files upon reboot, breaking the anonip-service services.
