nanosleep: Pass NULL when rem == NULL on ports with __TIMESIZE != 64

Browse Source 
On ports with __TIMESIZE != 64 the remaining time argument always receives
pointer to struct __timespec64 instance. This is the different behavior
when compared to 64 bit versions of clock_nanosleep and nanosleep
functions, which receive NULL.

To avoid any potential issues, we also pass NULL when *rem pointer is
NULL.
