The cargo test preflight step is slow and unnecessary since the verify
step already runs tests after implementation.

Each script node runs in a fresh sh shell, so sourcing .cargo/env
in the toolchain node doesn't persist. Symlinking into /usr/local/bin
puts cargo, rustc, clippy etc. on the default PATH for every node.

The `. $HOME/.cargo/env` was running inside a subshell so the PATH
change didn't persist to the subsequent `cargo --version` command.
