tools/nolibc/gettimeofday: avoid libgcc 64-bit divisions
timespec::tv_nsec is going to be 64-bit wide even on 32-bit
architectures. As not all architectures support 64-bit division
instructions, calls to libgcc (__divdi3()) may be emitted by the
compiler which are not provided by nolibc.
As tv_nsec is guaranteed to always fit into an uint32_t, perform a
32-bit division instead.
