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
