Update usr/share/rear/layout/prepare/GNU/Linux/15_include_drbd_code.sh
Dag has introduced filesystem detection of USB_DEVICE in 20_check_usb_layout.sh.
Therefore, decided if btrfs is found as a filesystem that relabeling is only a
small extra task for this script. However, default format is still ext3 if none found.

improve systemd functionality for udev stuff on fedora 17.

seems to be broken in fedora 17 (in the rescue image that is).
