Subject: Fixed memory leak in QPA/Lighthouse event handling.

The WindowSystemEvent class needs a virtual destructor, or sub-classes
with non-POD members will leak memory and their member's destructors
don't get called.

This is a backport, the bug was already fixed in Qt 5 as
4ab6860172e14b0047e56ab.
