drm_hwcomposer: Stop UEvent thread in ResourceManager destructor
When the ResourceManager is destructed, the UEvent thread continues to
run in the background.
Change the blocking read call to poll, and create an eventfd on which to
poll as well. When ResourceManager is destructed, write to the eventfd
to wake the UEvent thread, which can then exit cleanly.
