staging: Add BB_SETSCENE_VERIFY_FUNCTION2 for bitbake runqueue changes

We're about to rewrite the data structures in taskdata/runqueue in bitbake
and we 'leaked' knowledge about those structures to this single function.

Add a 'v2' function definition for use with the newer bitbake, the older
one can remain for compatibility for a while, then be removed. The function
is comparatively simple and rarely changes.
