Fix to speed up boot to BMC Ready state

The legacy services(like system and chassis) was assigned nice value
of 19 to alleviate CPU stress at boot time. The systemd bootchart
showed that many services are dependedent on the system service. The
nice is set to default value of 0 and there is a consistent improvement
of ~10 sec in BMC getting to ready state.
