chromium: Fix updater for version 26 and newer.
The updater was actually getting the -lite version, which our expression won't
build with, except if we switch some bundled dependencies to those in nixpkgs.

Of course the problem with fetching version 27 was me being stupid and using a
case statement in the updater, as if there won't be any version after 26 ;-)
