kconfig: qconf: drop Qt4 support

It is possible to keep this compatible with both Qt4 and Qt5, but not
worth the efforts any more; it would require us to test this on both of
them, and prevent us from using new features in Qt5.

Qt5 was released in 2012, and now widely available.

Drop the Qt4 support.
