Compile redis with full systemd support when the chosen init system
is systemd.

Enabling systemd supervision allows redis to communicate the actual
server status (i.e. "Loading dataset", "Waiting for master<->replica
sync") to systemd, instead of declaring readiness right after
initializing the server process.
