cbor_print_opaq() generates the member name of an opaque list/leaf-list on the first instance and frees it twice when that instance is also the last one (ASan: double-free), while with several instances the name is already gone when the array is completed so the whole list is silently dropped from the output; any data holding an unknown list inside anydata (e.g. {"cbor-test:anydata-payload":{"foo:bar":[{"x":"y"}]}} parsed with default options) or parsed with LYD_PARSE_OPAQ triggers it when printed as CBOR, so generate the name once the array is completed like cbor_print_leaf_list() does, and test_opaque_list covers both cases.
