parser json BUGFIX parsing object key-value pair in lydjson_data_skip()

After a key-value pair was successfully parsed in lydjson_data_skip()
lyjson_ctx_next() parses the next key and returns LYJSON_OBJECT.
Add a missing check to see whether a nested object was actually parsed
or whether it was the next key.

Remove sublevel checks for LYJSON_OBJECT_EMPTY and LYJSON_ARRAY_EMPTY.
In the case of empty objects, jsonctx->depth doesn't change after calling
lyjson_ctx_next(), so sublevel is never increased.

This issue was found by OSS-Fuzz in lyd_parse_mem_json.
