package/qt5/qt5base: disable predefined -Og optimization

Starting from Qt5 5.9.0, -optimize-debug is enabled by default for
debug builds causing -Og flag to be appended to CFLAGS and
consequently override TARGET_CFLAGS. We don't want this so let's pass
-no-optimize-debug to QT5BASE_CONFIGURE_OPTS if QT5_VERSION_LATEST=y.
