Packaging: re-enable XDG_Shell for Tizen
The Weston has been upgraded to 1.5 and XDG_Shell basics for Weston 1.5 have been in oz-wl.
So we think it's time to re-enable it now. Meanwhile some related issues are under fixing. More changes will come in.
[Tizen] hardcode OZONE_WAYLAND_USE_XDG_SHELL env in service file

This change tells ozone wayland backend
that shell is supporting unstable xdg-shell.

This is needed for by tizen's Application.hide().

Alternative would be store this var in system wide env
ie: /etc/profile/crosswalk.sh
And eventually force a login shell (sh -l -c "...")
in this service file.

But for performance concern it's hardcoded there,
this change may be reverted later
if Tizen sessions decide to use login shells then it will work same.
