wasi.c: report no environment variables available

I moved part of the compiler that checks environment variables to the standard library, so it doesn't have access to `build_options.only_c` anymore, which means some environment variable checks are leaking into the zig1.wasm build of zig. This logic still makes it return "no environment variables found" though.
