macOS ARM - incorrect process CPU times

[andrewkroh]

Based on similar code in other projects it looks like the process CPU times may not be scaled correctly on Apple M1 / M2 hardware (and are off by a factor of 125/3).

	status.CPU.User.Ticks = opt.UintWith(uint64(info.ptinfo.pti_total_user) / uint64(time.Millisecond))
	status.CPU.System.Ticks = opt.UintWith(uint64(info.ptinfo.pti_total_system) / uint64(time.Millisecond))
