[Toaster] [PATCH 04/18] toaster: layerindex updater Take into account layers being predefined

[Michael Wood]

As we can now provide layer definitions through fixtures we need to be
more clever how we update the metadata in the database to avoid
duplicate metadata being created. To do this we make more effort to
match existing data in the database and update only the fields which
will be better provided by the layer index.

This removes the need for us to special case layers which are provided
as part of poky such as openembedded-core or meta-poky which exist on
the layerindex but with different git urls.
