Setting XDG_RUNTIME_DIR variable in profile env would not help for
log-in users except weston.
There is now a global /run/wayland-0 socket that gets created for
wayland clients to access, let's use that instead.

weston-init: Stop running weston as root
Running the weston compositor as the root user is an insecure default
behavior for OE-core. We can do much better, at least when using
systemd. Change the recipe to create a dedicated "weston" user and start
weston as this user. The systemd service and socket units are no longer
template units, as there were several inconsistencies in the templates.
Instead, there is now a global /run/wayland-0 socket that gets created,
and systemd will start weston on demand when a client connects to that
socket or when attempting to reach graphical.target, whichever comes
first. This also allows downstream users to easily change the behavior
so that weston *only* starts on demand by adding a drop file. Access to
the global socket is controlled by a "wayland" group; any user that is a
member of the group can use the socket to talk to the compositor. This
also satisfies another use case where another systemd service might
start a graphical application that needs to display with weston (e.g. a
single function device in kiosk mode). Finally, the udev rules for
starting weston with the existance of a DRM device have been removed.
Being WantedBy= a graphical target should eliminate the need for this
behavior, and having it present makes it difficult for downstream users
to start weston on demand (having to override the udev rules).
