ssh/terminal: set termios VMIN and VTIME in MakeRaw

Browse Source 
The Solaris version of MakeRaw already sets VMIN and VTIME explicitly
such that a read returns when one character is available.
cfmakeraw (whose behavior MakeRaw replicate) in glibc and the BSD's libc
also set these values explicitly, so it should be done in the Linux/BSD
versions of MakeRaw as well to be consistent.
