Fix GitHub token auto discovery (#1335)

* Fix GitHub token auto discovery

Fixed #1333

 - Rm dep `gh-token` since it is broken and we can simply run
   `gh auth token` in `cargo-binstall` instead.
 - binstalk-downloader: Make sure GitHub token is at least 40B long
   and other than the `_`, composes of only alphanumeric characters.
 - Warn on failure to read `git/credential` files
 - Optimize `try_from_home` to avoid heap allocation of `PathBuf`
