self: Use the new 'imported-files'. 

That way, the source of most nodes is now a content-addressed store item
instead of a derivation.

* guix/self.scm (<file-mapping>): New record type.
(file-mapping-compiler): New procedure.
(scheme-node): Use 'file-mapping' instead of 'imported-files'.
(imported-files): Remove.
