tools/nolibc: prefer explicit 64-bit time-related system calls

Make sure to always use the 64-bit safe system calls
in preparation for 64-bit time_t on 32-bit architectures.

Also prevent issues on kernels which disable CONFIG_COMPAT_32BIT_TIME
and therefore don't provide the 32-bit system calls anymore.
