MINOR: mux-h1: Don't add Connection close/keep-alive header for 1xx messages

No connection header must be added by the H1 mux in 1xx messages, including
101. Existing connection headers remains untouched, especially the "Connection:
upgrade" of 101 responses. This patch only avoids to add "Connection: close" or
"Connection: keep-alive" to 1xx responses.
