MINOR: mux-h1: Don't emit C-L and T-E headers for 204 and 1xx responses

Browse Source 
204 and 1xx responses must not have any payload. Now, the H1 mux takes care
of that in last resort. But they also must not have any C-L or T-E
headers. Thus, if found on the sending path, these headers are ignored.
