[PATCH] event: Fix event handlers to raise SkipPackage

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If an event handler triggers a SkipPackage event, we really want that
event to be received and processed by the higher code levels. Currently
it was getting caught and ignored which was leading to recipes
being present when they clearly shouldn't have been.
