    Fix build on Cygwin, bug 665368
    
    Cygwin uses gio-unix, not gio-windows.
    
    Cygwin has posix_openpt but not getpt, which is nonstandard. Either will
    work in pty_open.c, but in vinagre-ssh.c, USE_PTY is determined by
    HAVE_GRANTPT, which is true on Cygwin. Using grantpt as the determining
    factor across the board prevents any chance of error.
