rust: Include Soong module name as metadata
If we want to build a component which uses two versions of a crate in
the dependency graph (for example, libc in std and libc from
external/crates), Rust requires at least one of them have a metadata
field to differentiate them.
Since Soong module names should be distinct for a given target, they
should serve as metadata.
