    rng-tools: start rngd early in the boot process again
    
    It do make sense to start rngd early in the boot process because
    otherwise we would need to track every service that might need entropy
    and explicitly configure it to start after rngd.
    
    When used with systemd rngd blocked the shutdown process because it
    simply missed the proper unit configuration. As the systemd
    documentation explains, when using DefaultDependencies=no one also
    have to explicitly configure the unit to properly stop at some point.
    This is normaly achieved by having Before=shutdown.target and
    Conflicts=shutdown.target set for the unit.
    
    To have rngd started early again we reverte the changes done to
    rngd.service in commit edf7606822 (rng-tools: fix rngd blocks system
    shutdown). To have it properly stopped on shutdown we also add
    Before=shutdown.target and Conflicts=shutdown.target.
