Forbid Rust source_sets.

These are not currently used by either Fuchsia or Chromium,
as current best practice is to use groups instead. It's not clear
what the purpose of a Rust source_set would be, since only the
crate_root is fed to rustc anyway; any other sources just act
as implicit dependencies.

A subsequent commit will allow Rust targets to depend upon C++
source sets, and that change is much less invasive if Rust
source sets are not possible.
