Subject: [PATCH] build/cargo: Set default value of arguments for build phases.

This will make it easier to use these phases in other bulid systems.

* guix/build/cargo-build-system.scm (unpack-rust-crates, configure, build)
(package, install): Set default value for arguments specific to this build
system.
