Test script to check functional usage of systemd.

Following check are implemented :
Check systemd starts with PID 1.
Check if systemctl start and stop option is able to work for a service.
Check for failed service on device using systemctl status.
Script returns with exit code 1 if any of the subtest is failed.
Usage Command Verified : ./run-test.sh systemd
