login: add rule for qemu's pci-bridge-seat
Qemu provides a separate pci-bridge exclusively for multi-seat setups. The normal pci-pci bridge ("-device pci-bridge") has 1b36:0001. The new pci-bridge-seat was specifically added to simplify guest-side multiseat configuration. It is identical to the normal pci-pci bridge, except that it has a different id (1b36:000a) so we can match it and configure multiseating automatically. Make sure we always treat this as separate seat if we detect this, just like other "Pluggable" devices. (David: write commit-message)
