X11: Don't delay delivery of focus events unless we just changed vidmodes.

Normally there's a 200 millisecond delay on all focus events in case there
was a vidmode change, now we note the last vidmode change and only impose this
delay if a change happened extremely recently.

Thanks to Epic Games for reporting this issue.
