In systemd.bbclass, it will replace criterion command 'type systemctl'
with 'systemctl' without any argument to judge whether command systemctl
is available. The change is to fix install/remove package error in
container when command systemctl exists but not callable.
Make native systemctl wrapper prints help mesages if called without any
argument to follow the update.
