Fix for gphoto2 breakage in Kubuntu

It seems gphoto2 got broken on latest Kubuntu 6.10 (not sure if it's a backport or what) so one can no longer use digikam.

I got it working following the suggestion on Ubuntu bug 91250 that is basically changing BUS!="usb*", GOTO="libgphoto2_rules_end" to SUBSYSTEM!="usb*", GOTO="libgphoto2_rules_end" in /etc/udev/rules.d/45-libgphoto2.rules
