util: Drop unused variable num_chars

clang complains:

../../lib/util/genrand_util.c:99:9: error: variable 'num_chars' set but not used [-Werror,-Wunused-but-set-variable]
        size_t num_chars = 0;
               ^

That is, the variable is initialised and incremented but the value is
never used.
