Verify the presence of systemd

systemd is a software suite that provides an array of system components for Linux operating systems. systemd's primary component is a "system and service manager"

Sometimes the Debian updates were trying to install systemd package.
When installed, systemd service management modifies the service startup parameters with an unexpected behavior.
Especially for the memcached service that is a central service for Artica.
When using 4.30.000000 Service Pack 211 or above, Artica detects the presence of systemd and disable the memcached daemon management from systemd.
