[PATCH v9 27/29] rust: alloc: update module comment of alloc.rs

[Danilo Krummrich]

Before we remove Rust's alloc crate, rewrite the module comment in
alloc.rs to avoid a rustdoc warning.

Besides that, the module comment in alloc.rs isn't correct anymore,
we're no longer extending Rust's alloc crate.
