grafts: Consider all the outputs in the graft mapping.
Before that, outputs of a derivation could be left referring to the ungrafted version of the derivation. * guix/grafts.scm (graft-derivation)[outputs]: Change to a list of name/file pairs. * guix/grafts.scm (graft-derivation)[build]: Add 'old-outputs' variable and use it when computing 'mapping'. Use 'mapping' directly. * tests/grafts.scm ("graft-derivation, multiple outputs"): New test.
