_update_array_map_entry_with_handle doesn't handle > 255 map entries correctly.

[Alan-Jowett]

uint8_t* entry = &map->data[*key * map->ebpf_map_definition.value_size]; is incorrect. *key is a pointer to uint8_t, not an integer index. It should be (uint32_t)key to match the pattern used elsewhere for array index calculation.

Suggested change:

• uint8_t* entry = &map->data[*key * map->ebpf_map_definition.value_size];
  

• uint8_t* entry = &map->data[*(uint32_t*)key * map->ebpf_map_definition.value_size];
