logind: udev rule for Parallels video adapter

This enables graphical capability for a video adapter of Parallels
virtualization platform (Parallels Desktop for Mac product) which is not
a DRM device at the moment.

This fixes GUI in Fedora 29 guest on Parallels Desktop where gdm now
strictly checks for CanGraphical property of a seat, see [1].

Should be noted that there's no in-kernel driver for Parallels video at
the moment so device matching is done by vid/pid.
