firmware: implement canHandleBlob

Implement the canHandleBlob method.  For any blob_id specific command
from the manager level, it'll ask each handler if they support that
blob_id before passing it down.  The call is made against only the first
handler that responds in the affirmative.

If the client creates a new blob_id via an action, they are expected to
again enumerate the blobs to verify the operation -- although they don't
need to.  Any action that creates or deletes a blob_id will update the
firmwares list.

Operations are single-threaded.
