Give up on making clock_nanosleep() precise

Browse source 
Multiple projects I care about make the assumption that this isn't a
system call that sleeps for a particular number of nanonseconds, but
rather a function that parks processes on kernel scheduler quantums.
Anyone who wants the old behavior should use cosmo_clock_nanosleep()
