drm_hwcomposer: Make uevent listener standalone

1. DRM event listener doesn't work in this conditions, uevent blocks
   the thread and non-blocking select() doesn't make any sense.
   Remove DRM event handling for now.

2. UEvent listeren is common for all DrmDevices, therefore put it into
   ResourceManager class.
