http2: handle existing socket data when creating HTTP/2 server sessions
When emitting a 'connection' event to manually inject connections into a
server, it's common for the provided stream to already contain readable
data, e.g. after sniffing a connection to detect HTTP/2 from the initial
bytes.

Previously this was supported only for outgoing HTTP/2 sessions created
with http2.connect(). This change ensures that HTTP/2 over existing
streams is supported on both outgoing and incoming sessions.
