build: remove lint/dotfiles from release tarball

This removes the ability to run linting from the source tarball,
rationale being that developers should use a git clone instead.

Also, fix the path of removing artifacts from the openssl dependency
since it now lives in `deps/openssl/openssl/`.

Tarballs shrink with ~10%.
