HTTP3: fix invalid use of sendto for connected UDP socket
On macOS/BSD, trying to call sendto on a connected UDP socket fails
with a EISCONN error. Because the singleipconnect has already called
connect on the socket when we're trying to use it for QUIC transfers
we need to use plain send instead.
Fixes #4529
Closes https://github.com/curl/curl/pull/4533
