The generated wasm file should no include users' file path

[axetroy]

Running the command to compile

wasm-pack build --release --target bundler --out-dir out/bundler

and preview in Chrome

And we can see the path in the output file.

Usually, it has the risk of leaking user information.

I'm not sure which package(rust/wasm-pack/or other crate) generated this

This isn't a problem with wasm-bindgen or wasm-pack, but with Rust in general.

See https://doc.rust-lang.org/rustc/command-line-arguments.html#--remap-path-prefix-remap-source-names-in-output for how to avoid this.

Hopefully this can be more easily configured in the future: rust-lang/rfcs#3127.
