Add CGO_ENABLED=0 to Linux cross-compile targets; add Dockerfile

CGO_ENABLED=0 ensures a fully static binary that runs in Alpine without
glibc. Dockerfile copies both binaries into Alpine, installs cronie for
the awp-cli cron job, and mounts runtime data (players.json, static/,
logs/) from the host at runtime.
