package/nghttp2: security bump to version 1.57.0

Fix CVE-2023-44487: The HTTP/2 protocol allows a denial of service
(server resource consumption) because request cancellation can reset
many streams quickly, as exploited in the wild in August through October
2023.

Fix CVE-2023-35945: nghttp2 fails to release memory when PUSH_PROMISE or
HEADERS frame cannot be sent, and nghttp2_on_stream_close_callback fails
with a fatal error. For example, if GOAWAY frame has been received, a
HEADERS frame that opens new stream cannot be sent.
