Exclude more files from the published crate

[musicinmybrain]

There was an incorrect glob bench/* that was doing nothing, since the benchmarks are in benches/; when I corrected it to benches/*, cargo publish --dry-run failed:

error: failed to verify package tarball

Caused by:
  failed to parse manifest at `/home/ben/src/forks/oxipng/target/package/oxipng-9.0.0/Cargo.toml`

Caused by:
  can't find `zopfli` bench at `benches/zopfli.rs` or `benches/zopfli/main.rs`. Please specify bench.path if you want to use a non-default path.

…so I stopped trying to exclude the benchmarks from published crates at all.

---

Then, I added Dockerfile, index.html, and scripts/ to the list of paths to exclude from published crates.

Finally, I added some unnecessary “dotfiles” to the list of paths to exclude from published crates.

Some of this was suggested in a package review for Fedora Linux.

Thanks for this, it sounds sensible.
Just one comment: The index.html file seems to be for a very old set of docs that no longer exists. We should just delete this file.

Thanks for the suggestion! I removed index.html from the repo and from the excludes.

Looks good to me! Can merge once @AlexTMjugador also approves.
