Subject: cargo-build-system: Accept a #:features argument

* guix/build/cargo-build-system.scm (build, install): Pass the features
  to cargo.
  (check): Remove indirection layer for consistency with build and
  install.
* guix/build-system/cargo.scm (cargo-build): New argument; pass it into
  the builder.
* gnu/packages/rust-apps.scm (ripgrep): Use the new argument instead of
  a custom phase.
