Fix on GCC v10:

    tools/nfctool/adapter.c: In function ‘adpater_print_targets’:
    tools/nfctool/adapter.c:69:33: error: cast between incompatible function types from ‘void (*)(guint32,  gchar *)’ {aka ‘void (*)(unsigned int,  char *)’} to ‘void (*)(void *, void *)’ [-Werror=cast-function-type]
       69 |  g_slist_foreach(adapter->tags, (GFunc)adapter_print_target, "tag");
          |                                 ^
