[release-branch.go1.19] runtime: fix usleep on linux/PPC64 The existing implementation fails to convert the remainder microseconds to nanoseconds. This causes sysmon to consume much more cpu, and generate lots of context switches. We can also do a little better here to avoid division by a constant. I used go to determine the magic numbers.
