rust: fix rust build-support debug build type

[AtkinsChang]

Motivation for this change

buildType introduced in #56540 is not working because there is no --debug options for cargo.

According to cargo:

Compilation can be configured via the use of profiles which are configured in
the manifest. The default profile for this command is `dev`, but passing
the --release flag will use the `release` profile instead.

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Assured whether relevant documentation is up to date
• Fits CONTRIBUTING.md.
