meta-phosphor: busybox: add `top` features for SMP
High loads within a server can severely impact performance and response
times. Adding `top` features for SMP to identify which process(es) or
service(s) causing high loads significantly on which core.
Tested:
root@evb-npcm845:~# top
Mem: 217800K used, 630044K free, 14412K shrd, 0K buff, 99832K cached
CPU: 0% usr 2% sys 0% nic 48% idle 48% io 0% irq 0% sirq
Load average: 0.02 0.01 0.00 1/182 1912
PID PPID USER STAT VSZ %VSZ CPU %CPU COMMAND
