rules: do not put raw1394 in "video" group

A note on /dev/raw1394's security implications:
1. You cannot access local memory through raw1394, except
for ROMs and CSRs that are exposed to other nodes any way.

2. It is extremely hard to manipulate data on attached
SBP-2 devices (FireWire storage devices).

3. You can disturb operation of the FireWire bus, e.g.
creating a DoS situation for audio/video applications, for
SBP-2 devices, or eth1394 network interfaces.

4. If another PC is attached to the FireWire bus, it may be
possible to read or overwrite the entire RAM of that remote PC.
This depends on the PC's configuration. Most FireWire controllers
support this feature (yes, it's not a bug, or at least wasn't
intended to be one...) but not all OSs enable the feature.

Actually, a cheap setup to achieve #1 by #4 is to have two
FireWire controllers in the PC and connect them.
