description:
When not using the serial console while installing with sysinst,
switch all ports in /etc/ttys over to wsvt25.

For mixed setups that sometims do serial console and otherwise
frambuffer console, it would be better to leave console and constty as
vt100, but switch console to off and ttyE0 to on, but we do not want
to bother the user with tricky questions here and everyone switching
console types should have no problem changing this setup later,
or even deal with a serial console and TERM=wsvt25.
