server/client: use $WAYLAND_DISPLAY instead of $XDG_SESSION_ID in default socket path

Foot is a Wayland client and cannot be run outside of a Wayland
session. As such, it makes more sense to use $WAYLAND_SESSION instead
of $XDG_SESSION_ID in the default socket path since this makes it
clearer which Wayland session we belong to.

Closes #55.
