Fix showNormal() and friends for platforms with fullscreen hint

Don't call show() inside of QWidget, as that might make the window
fullscreen due to QStyleHints::showIsFullScreen().

This regression was introduced earlier when QWidget::show() gained
support for the hint. No auto test caught the problem, as the
affected platforms (EGL and QNX) are not CI-tested.
