grml-udev-config.grml-forensic: also react to block device *changes*

When executing `partprobe /dev/sda`, then partitions are
changed, removed and added again, while DISK_RO=0 is set
on the main block device (/dev/sda):

Explicitly pass block device name to the script, which should
make usage of script as standalone tool better.
