config: only default to xwayland persistence on old wlroots versions

This is a compile-time check, so it will be too conservative if somebody
updates wlroots after building labwc, but that is still better than the
alternatives.

*<core><xwaylandPersistence>* [yes|no]
Keep XWayland alive even when no clients are connected, rather than
using a "lazy" policy that allows the server to launch on demand and die
when it is no longer needed. Default is yes.
when it is no longer needed.
This is only temporarily defaulting to yes to avoid a bug that is
present in wlroots <0.18.2 resulting in a compositor crash when
performing a drag-and-drop action at the same time as the XWayland
server is shutting down. This will be reverted to a default "no" when
wlroots-0.18.2 can be linked with.
When labwc is compiled with wlroots 0.18.2 or later, the default is no.
When labwc is compiled with wlroots < 0.18.2, the default is yes to
avoid a wlroots bug that can result in compositor crashes when
performing drag-and-drop actions when the XWayland server is shut down.
Note: changing this setting requires a restart of labwc.
