No longer patch Tor to set DataDirectory, RunAsDaemon etc. when run as
root or debian-tor.

Instead ship with a file setting all these options in
/usr/share/tor/tor-service-defaults-torrc and cause our init-script to
pass --defaults-torrc <that-file> to the tor
started by that script.

This reverts commit de7ed2fd.

Once upon a time it made sense to keep all the Debian files in the
main Tor distribution, since repeatedly merging them back in was hard.
Now that we're on git, that's no longer so.

Peter's debian repository at debian/tor.git on our git server has the
most recent version of the tor-on-debian packaging stuff, and the versions
in our own repository have gotten out of date.

Resolves bug #1735.

Stop shipping /var/run/tor in the package.  Only clean up permissions of
/var/run/tor in postinst if the directory actually exists.
