    srp_daemon: Detect proper path to systemctl
    
    While debian uses /bin/systemctl, SUSE only supports /usr/bin/systemctl,
    causing srp_daemon to fail silently starting on all ports.
    Detect at built which path is the right one and use it.
    
    Fixes: b03beb142e0d ("srp_daemon: Call systemctl properly from udev")
