Revert setcap, update rust and crates

- Revert #3170 as discussed in #3387
  In hindsight it's better to not have this feature
- Update Dockerfile.j2 for easy version changes.
  Just change it in one place instead of multiple
- Updated to Rust to latest patched version
- Updated crates to latest available
- Pinned mimalloc to an older version, as it breaks on musl builds
