These examples have a gtk+3 dependency that can't be met on the ccmp13 due to
it being a headless device. Remove these examples from the packagegroups so we
can at least build the rest of the ML packages.
Note that all of ST's ML examples are GUI-based and will not be usable on the
ccmp13, but since the remaining examples don't have an explicit gtk+3
dependency, at least they won't trigger build errors when included in the
image.
