Otherwise curl may be told to use for instance pop3 to communicate with the doh server, which most likely is not what you want. Found through fuzzing.

doh did not time out properly. This change makes it return early with CURLE_OPERATION_TIMEDOUT.
In debug builds, doh could be configured to use any protocol, which lead to it trying to do doh over pop3 when the http fuzzer was running. It is now restricted to http and https.
