feature: Use `ps` as fallback to query CPU usage under macOS (#390)

When running without elevated permissions under macOS, sysinfo cannot
query states of processes by root user, which results in 0.0% CPU usage
for all this kind of processes (and state = Unknown).

Here we use `ps`, which has SUID, as a fallback to query CPU usages.
This can be potentially applied to other properties if needed in the
future (we'll need a proper struct and parser).
