Fix: bt2: use unsigned iteration variable

This fixes the following compiler diagnostic (gcc 9.1.0):

    bt2/native_bt.c: In function ‘_wrap_field_class_enumeration_unsigned_get_mapping_labels_for_value’:
    bt2/native_bt.c:9387:25: error: comparison of integer expressions of different signedness: ‘int’ and ‘uint64_t’ {aka ‘long unsigned int’} [-Werror=sign-compare]
     9387 |       for (int i = 0; i < *arg4; i++) {
          |                         ^
