[bug#74958] [PATCH rust-team 1/5] build/cargo.scm: Remove '--release' from default cargo-test-flags.

[Maxim Cournoyer]

The default behavior for 'cargo test' is to build in debug mode, and many test
suites expect support for things provided in this mode such as debug
assertions (see for example:
<https://github.com/google/zerocopy/issues/2143>).

* guix/build-system/cargo.scm (cargo-build): Remove '--release' from
 #:cargo-test-flags.
* guix/build/cargo-build-system.scm (check): Likewise.
