vim: Remove setting g:rustc_path

Having a fallback rustc executable in my Vim closure at all times looked
like a good idea in the first place, but since g:rustc_path is only used
for things like :RustRun it is of very limited use (only for standalone
Rust files).

I had exactly *zero* uses for that since I introduced it, so there is
really no need to bloat the closure size for something I don't use.
