Moved tests into gui/kernel/ and gui/qopengl/

This commit moves tests from test/auto/ into more appropriate
locations (i.e. matching the locations in the Qt source):

- qscreen and qwindow are moved into gui/kernel/
- qopengl is moved into gui/qopengl/

Note: qscreen is disabled for now since it is broken
on Linux (see QTBUG-22554).
