When do world buid, there comes below error:
| ERROR: Nothing PROVIDES 'gtk+3' (but /build/layers/oe-core/meta/recipes-gnome/libdazzle/libdazzle_3.30.2.bb DEPENDS on or otherwise requires it)
| gtk+3 was skipped: one of 'x11 wayland' needs to be in DISTRO_FEATURES
Add the check for GTK3DISTROFEATURES to make
the world build work even without GTK3DISTROFEATURES.
