[PATCH] runqueue: Add handling of virtual/xxx provider mappings

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

This firstly prints debug messages which show how bitbake decided to resolve
the virtual/xxx providers which is useful for debugging.

If the siggen has a tasks_resolved() method, it calls this, passing in
the mappings, allowing that to do things with the resolved names.
