src/lib/trace.c: Make address size generic

On platforms that didn't use 32-bit addresses, enabling the
    CONFIG_TRACE option (Trace function calls) would break the build due
    to a cast from a pointer of a different size.

This fixes this warning:
    src/lib/trace.c:29:58: error: cast from pointer to integer of different
    size [-Werror=pointer-to-int-cast]
