override user defined channel when using precompiled rustc

We need to override `rust.channel` if it's manually specified when using the CI rustc. This is because if the compiler uses a different channel than the one specified in config.toml, tests may fail due to using a different channel than the one used by the compiler during tests.

For more context, see https://github.com/rust-lang/rust/pull/122709#issuecomment-2165246281.
