[bench] Use higher resolution timer on POSIX
The timer used was only accurate up to 0.01 seconds. This timer is accurate up to 1 ns.
It is a monotonic timer that measures the real time difference, not on CPU time.
Copied the benchmark code from https://github.com/facebook/zstd/commit/6ab4d5e9041aba962a810ffee191f95897c6208e
