Document rootless Xorg

See void-linux/void-packages#13754

Maybe with elogind and the elogind build option in Xorg? I don't know if we should give instructions to build packages locally with xbps-src in void-docs.

Not sure if this is a terrible idea but adding the user to "input" group and change "needs_root_right" to auto, Xorg will run with normal priviledge.

Supposedly most of the reason for seatd and elogind existing is that being in input group is bad.

The input group grants read/write power to everything in /dev/input which is probably not what you want.
