smstools3: Move init script to use procd

* properly install config file
* prevent smsd from starting right after installation to prevent loss of data
  (make default device unavailable by turning configuration into comments)
* move init script to procd
* update init script priority to sane value
* log to syslog - at the moment via stdout and procd
  this is a workaround to force smsd to stay in the foreground
* the init script can't do a modem reset anymore
  use an alarmhandler script instead
* add a local patch to make all processes terminate if the main process dies
* take over the package as new maintainer
