wrapper.c: Fix fprintf argument warning

Fix a warning in cgroup_add_value_string() where '%d' was
being passed to fprintf when it should have been using '%ld'.

wrapper.c: In function ‘cgroup_add_value_string’:
wrapper.c:207:51: warning: format ‘%d’ expects argument of type ‘int’,
but argument 3 has type ‘long unsigned int’ [-Wformat=]
  207 |    fprintf(stderr, "value exceeds the maximum of %d
      characters\n",
      |                                                  ~^
      |                                                   |

  208 |     sizeof(cntl_value->value) - 1);
      |     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |     |
      |     long unsigned int
