packages: add NetBSD dtail pipeline (pi0/pi1, aarch64)

- Makefile target dtail-netbsd: cross-compile netbsd/arm64 (CGO_ENABLED=0,
  nozstd), package natively on pi0 with pkg_create, upload package plus
  pkg_summary.gz to the PV at netbsd/10.1/packages/aarch64/ via f0
- scripts/pkg-dtail-netbsd.sh: NetBSD pkg_create packaging (prefix /,
  root-owned files via @owner/@group plist directives)
- frontends: NetBSD dserver rc.d script, dtail.json (absolute cache
  paths), and key-cache helper templates
- pkgrepo nginx: serve /netbsd/ with autoindex
- Fix stale ROCKY_ARM_BUILD_HOST: pi0 was re-imaged to NetBSD, aarch64
  RPMs are built on pi2
