Update nut-v2.8.1 packaging

Lessons learned from https://github.com/OpenIndiana/oi-userland/pull/14630 :
* avoid delivering "driver" actions after all - they do not let NUT user
  get permissions to just the devices with wanted USB VID:PID, and it
  conflicts with ugen package overall :\ End-users with USB UPSes would
  probably have to set `user=root` in `ups.conf` sections, at least for now.
* make sure SMF method scripts are executable
* add a history file to facilitate upgrades from earlier 2.7.4 packages
* revive "nut-bins" for multiple inheritance from 2.7.4 package names
  in case of upgrades (nut-server vs. nut-clients now)
