[PATCH evdev] evdev: enable option "GrabDevice" by default for non-seat0 seats (#69478)

[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",
option "GrabDevice" is enabled by default (no need of enabling it
in xorg.conf's "InputClass" section).
