bitbake: cooker/providers: Only add target to world build if task exists

A "bitbake world -c unpack" currently breaks as not all tasks have an
unpack task. This change allows addition of world targets only if the
specified task exists which makes certain commands possible when otherwise
you just get errors which can't easily be avoided.
