rules: set ID_BUS=bluetooth for any device with id/bustype attr of 0x0005 (#5539)

Not all bluetooth devices come through the bluetooth subsystem and those that
don't currently lack the ID_BUS=bluetooth env. This again fails to apply udev
rules and/or hwdb entries that rely on the bluetooth bustype to be set.

Fix this by checking the attribute id/bustype on the device instead of just
the subsystem.

Fixes #4566
