Start/Stop unbound_monitor when unbound is started/stopped
Update unbound to 1.4.20_4
There should only be one unbound monitor running at any given time.

Script checks the number of running instances of itself and exits if
more than two. Since there should only be one instance running (itself)
it should check for more than one.

There should only be one instance of unbound monitor running
Fix unbound_monitor.sh (Ticket #2817)

. Use a PID file to keep track if it's running or not
. Move it to /usr/local/bin, it doesn't need to be started by
  rc.start_packages since it's already called by unbound.inc
. Define PATH and remove complete path for all binaries
. Remove unbound initscript symlink created when it's installed by a PBI
  package
. Bump unbound to 1.4.20_5
