This update fixes the following issues for parkverbot:
- Update to new upstream release 1.1 (bugfix release)
* Fixed passing wrong type to ioctl, which made a 32-bit parkverbot exit and not run at all (bnc#801367)
* Read all disks, rather than a single one, per interval
- systemd is not a runtime requirement
- Verify GPG signature.
- Replace bad signature by a new one
