[PATCH] xfree86: Keep a non-seat0 X server from touching VTs (#71258)

This is my first atempt to block VT access to non-seat0 X servers.
If -seat option is passed with a value different from seat0,
X server won't call xf86OpenConsole().
This is needed to avoid any race condition between seat0 and
non-seat0 X servers. If a non-seat0 X server opens a given VT
before a seat0 one which expects to open the same VT, one can
get an inactive systemd-logind graphical session for seat0.
This patch was first tested in a multiseat setup with multiple
video cards and works quite well.
I suppose it can also make things like DontVTSwitch and -sharevts
meaningless for non-seat0 seats, so it may fix bug #69477, too.
