Add tests of the various testlib definition possibilities.

The behavior of QTEST_MAIN depends on whether QT_GUI_LIB or QT_WIDGETS_LIB
is defined. It could create a QGuiApplication or QApplication which
could cause linking issues if the corresponding library is not linked to.

The failure cases are also tested.
