[PATCH] main/runqueue: Add --setscene-only option to bitbake

[PATCH] main/runqueue: Add --setscene-only option to bitbake

[Richard Purdie]

Its turning out that we really need a way to have bitbake just run
the setscene tasks but not any real tasks, particularly for SDK
operations.

Add an option for this since its pretty straight forward. This allows
various nasty workarounds in OE-Core to be removed.
