While we support
layers:
.: excluded
this is effectively the same as leaving out the layers property: The
repository itself will always be added as layer to bblayers.conf. This
prevents using kas to checkout layer-free repositories as well, e.g.
bitbake in case oe-core is used.
Add support for that be converting a non-existing layers property into
layers:
.:
internally and removing the special case from Repo.layers which assumed
that layers=None meant the above.
