[PATCH] rust: macros: fix indentation in `module!`'s doc comment

[Yutaro Ohno <yutaro.ono.418@gmail.com>]

Clippy warns about list content in a doc comment that doesn't have extra
spaces at the beginning of a new line [1], like this:

```rust
/// * Do nothing.
/// * Then do something. Whatever it is needs done,
/// it should be done right now.
```

The suggested format is:

```rust
/// * Do nothing.
/// * Then do something. Whatever it is needs done,
///   it should be done right now.
```

This commit adds extra indentation to the `module!`'s doc comment to
suppress the warning.
