devtool: if workspace layer exists, still ensure it's in bblayers.conf

When we run devtool, if the workspace layer already exists but isn't in
bblayers.conf (perhaps because it was previously created but
subsequently removed from bblayers.conf by the user) then we should add
it and notify the user, otherwise devtool operations won't work.
