[PATCH] xfree86: disable VT switching/enable VT sharing by default for non-seat0 seats (#69477)

[Laércio de Sousa]

This patch contributes to fill the remaining gaps which make
systemd-multi-seat-x wrapper still necessary in some multiseat setups.

When option "-seat" is passed with an argument different from "seat0",
the following xf86Info properties are set to TRUE by default:

* dontVTSwitch (no need of enabling ServerFlag option "DontVTSwitch" in xorg.conf)
* ShareVTs (no need of passing -sharevts option)

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=69477
