Peter Hutterer d625520be1 udev: update rules to handle bind/unbind events
Summary: we expect add, change or remove but kernel 4.12 added bind and
unbind. These events were previously discarded by udevd. Our rules should
handle any event *but* remove, so update as suggested in the announce email
linked below.

For a longer explanation, see the system 247rc2 announcement
