Bug 13896: Fix pid file creation, use proper directory instead of /tmp/

daemon uses by default /tmp/ for pid files, if they are unspecified.
Pass the right directory to daemon, so it knows where to put the pid file.

TEST PLAN
---------
1) Roll a distribution and confirm it works.

OR

1) Hack all the /var directories to point to git directories
2) Add a dummy user for the instance name
3) sudo the script with the faked instance name.
   -- the daemon should be running and the pid file should be in
      the expected directory.

The first way is the proper way to test, I did the latter. :)
