No longer need the trick for fast clock after we left centos7/rhel7  behind

- * This is a hack to avoid the slow clock computations on RHEL7/CentOS 7 due to using systemcalls.
- * This brings cost down from 550-560ns to 18-19ns on a Intel Haswell 2680 cpu.
- * We are providing the symbols here so they will take precedence over the ones in the standard library.
- * We rely on the linker do handle correct symbol resolution.
- * TODO: Once we are off the ancient platforms like Centos 7/ Rhel 7 we can drop this workaround.
