posix-timers: Accept NULL clock_getres() output in stubs
With CONFIG_POSIX_TIMERS disabled, clock_getres() returns -EFAULT for a
supported clock when the result pointer is NULL. POSIX permits a NULL
result pointer to suppress returning the clock resolution.
Only copy the result when a destination is provided, in both the native
and time32 stubs. This matches the full POSIX timer implementation and
preserves clock ID validation.
Fixes: baa73d9e478f ("posix-timers: Make them configurable")
Fixes: d822cdcce43f ("posix-timers: Move compat versions of clock_gettime/settime/getres")
