🐛 Fix act_runner download: repo renamed, new binary names 🐛

The gitea/act_runner repo was renamed to gitea/runner and binary
filenames changed from act_runner-{ver}-linux-{arch} to
gitea-runner-{ver}-linux-{arch} (with version stripping the leading
'v'). The old URLs returned 404 causing every build to fail.
Also adds resilience for builds where gitea.com is unreachable:
- 30s connect timeout / 45s max-time on API calls
- Pinned fallback version (v1.0.8) used when API returns nothing
- Fallback direct URL constructed from version tag without API
- Empty-URL guard before curl invocation prevents blank-argument error
- rootfs/root/docker/setup/05-custom.sh: fix repo path gitea/act_runner → gitea/runner, fix binary name pattern, add fallback version, add fallback URL construction, add empty-URL guard
