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

IIRC we chose to use '--release' for cargo-test-flags to minimize the
amount of rebuilding we did with each package.  If the tests are
expected to be run not in release mode then I guess we should change it.

I'll apply the patch to rust-team and then go through and see about
removing the cargo-test-flags from various packages.
