rust: Accept generated sources for main.rs There are still caveats here. Rust/cargo handles generated sources by writing out all targets of a single repo into a single output directory, setting a path to that via a build-time environment variable, and then include those files via a set of functions and macros. Meson's build layout is naturally different, and ninja makes working with environment variables at compile time difficult. Fixes #8157

# Doesn't actually use gen.py as input, just a limitation of generators
