meta-agl-bsp: make sure weston user is in display group for rcar3

Add a meta-rcar-gen3 specific weston-init bbappend to add the
weston user to the display group.  This is preferable to unmasking
the bbappend in upstream meta-rcar-gen3, as we do not want any of
the other changes it contains (or may contain).  This change is a
bit of a stopgap required for running weston or agl-compositor as
the weston user without the agl-driver user session unit in e.g.
the agl-image-weston image or the KVM or IC host images.
Future work will try to align the required groups with upstream
systemd-udevd expectations.
