frontends + packages: add dserver/dtail support for FreeBSD and Rocky

Adds FreeBSD .tpl variants of the existing dserver templates and a
matching pkg-dtail-freebsd.sh packaging script, plus a pkg-dtail-rpm.sh
script and packages/files/dtail-rocky/ (systemd units, key-cache script,
dtail.json) for the Rocky Linux dtail build.
