vte: set FLAG_USE_C1 when C1-8bit mode is requested

Browse Source 
We currently do not support sending C1 controls as 8bit characters because
this doesn't make any sense with UTF-8. However, in 7bit/8bit
compatibility mode the client can request this. As nearly all clients are
backwards compatible to VT100 they also support C1 controls as 7bit
sequences, though, so there is really no time pressure to implement
FLAG_USE_C1.
