refactor thrd_sleep and nanosleep in terms of clock_nanosleep
for namespace-safety with thrd_sleep, this requires an alias, which is also added. this eliminates all but one direct call point for nanosleep syscalls, and arranges that 64-bit time_t conversion logic will only need to exist in one file rather than three. as a bonus, clock_nanosleep with CLOCK_REALTIME and empty flags is now implemented as SYS_nanosleep, thereby working on older kernels that may lack POSIX clocks functionality.
