derivations: build-expression->derivation: Builder only refers to sources.
* guix/derivations.scm (build-expression->derivation)[source-path]: New
procedure.
[builder]: Pass only sources as references. This fixes a bug whereby
changing a fixed-output drv referred to by a builder would cause the
builder's hash to change, thereby leading to a full rebuild.
* tests/derivations.scm ("build-expression->derivation with a
fixed-output input"): New test.
