terminal: Set K_RAW and term raw mode on FreeBSD

Browse source 
Taken from X11, weston and consolekit2 ports for FreeBSD.

Setting just K_CODE as done before makes input seemingly have no ill
effects, but it is still buffered and possibly send to the terminal
after application exit if stdin is never drained. Setting raw mode
appears to be needed to solve that issue.

A K_OFF-like VT keyboard setting like Linux has would seem more
appropriate, but that is not currently available to us on FreeBSD.
