UDP Proxy: Don't drop CID records

ApplicationData records are not protected against loss by DTLS
and our test applications ssl_client2 and ssl_server2 don't
implement any retransmission scheme to deal with loss of the
data they exchange. Therefore, the UDP proxy programs/test/udp_proxy
does not drop ApplicationData records.

With the introduction of the Connection ID, encrypted ApplicationData
records cannot be recognized as such by inspecting the record content
type, as the latter is always set to the CID specific content type for
protected records using CIDs, while the actual content type is hidden
in the plaintext.

To keep tests working, this commit adds CID records to the list of
content types which are protected against dropping by the UDP proxy.
