avformat/hls: disable http_persistent/http_multiple with custom io_open
Both rely on the AVIOContext being backed by the builtin URLContext.
When the API user overrides io_open, the keepalive path asserts on the
missing URLContext and the http_multiple auto-detect probe fails on
every read. http_multiple=1 still works even with custom IO.
