eglfs: Avoid unexpectedly flushing QPA input events

Browse Source 
Flushing all events to ensure that the expose (or other queued events) get
processed right away is dangerous. Instead, pass ExcludeUserInputEvents like
many other platform plugins do. This way queued input events do not get
processed at an unexpected point in time and so do not interfere with modal
dialogs for instance.
