build-system: cargo: Handle Cargo.lock file not present.

* guix/build-system/cargo.scm (cargo-build): Add src output.
  (private-keywords): Add #:outputs.
* guix/build/cargo-build-system.scm (configure): Use /share/rust-source
  when replacing inputs.
  (build, check): Don't do anything when there isn't a Cargo.lock file
  present.
  (install): Install sources to src output. When a Cargo.lock file is
  present use cargo install to install binaries to out.
* guix/import/crate.scm (make-crate-sexp): Importer uses the src output
  for crate inputs by default.
* guix/import/utils.scm (package-names->package-inputs, maybe-inputs,
  maybe-native-inputs): Take an optional output argument.
* tests/crate.scm (crate->guix-package test): Update.
