winex11.drv: Correct a full screen condition.

The if condition here came from 47c54c4ae7f235780a55ddf670503db4afc11055,
which is to detect full screen window.

However, according to tests in previous commit, there is possibility
that a window without setting WS_CAPTION is not full screen, for example,
main window of Tencent WeChat. And windows like this can also be maximized
or restored. So that we can not treat WS_CAPTION as our full screen condition.

This fixes maximizing Tencent WeChat by dragging it to screen edge.
