bitbake: runqueue: Handle deferred task rehashing in multiconfig builds

Browse Source 
If the hash of a task changes and that hash is a deferred task (e.g. a multiconfig
build), we need to ensure that the hash change propagates through to all the tasks
else the build will run multiple copies of the task, sometimes with oddly differing
results as the outhashes of native tasks built in differing locations can confuse
things.
