sysutils/backrest: New port: Web UI and orchestrator for restic backup

Backrest is a web-accessible backup solution built on top of restic.
Backrest provides a WebUI which wraps the restic CLI and makes it
easy to create repos, browse snapshots, and restore files. Additionally,
Backrest can run in the background and take an opinionated approach
to scheduling snapshots and orchestrating repo health operations.
