vnc: use booleans for vnc_connect, vnc_listen_read and vnc_display_add_client

Some arguments to these functions are booleans - either by declaration,
or by actual usage, but sometimes value of 0 or 1 is passed for a bool,
and sometimes it is declared as int but a bool value, or true/false,
is passed to it instead.  Clean it up a bit.
