Yong Tang 4b5413396a Fix wrong CPU count after CPU hot-plugging 
This fix tries to address issues raised in #23768 where the CPU count
is not updated after cpu ho-plugging.

This fix follows the suggestion from #23768 and replace go's `runtime.NumCPU()`
with `sysconf(_SC_NPROCESSORS_ONLN)` so that correct CPU count could
be obtained even after CPU hot-plugging.

This fix is tested manually, as is suggested in #23768.

This fix fixes #23768.

The NumCPU() in Linux is based on @wmark 's implementation.
