Subject: [PATCH 3/3] use wlroots backend with unknown compositors

The description of the LXQtPanelApplicationPrivate::loadBackend() method
already states that if we cannot identify the correct backend for a
Wayland session, we should fall back to the wlroots backend module. This
is reasonable given how broadly the wlr protocols are implemented.
However, this was not happening due to a small error where we checked for
the wlroots string in XDG_CURRENT_DESKTOP, which is not a valid option.

This change fixes this by checking XDG_SESSION_TYPE for "wayland" instead.
As this is fallback logic, this is safe as the preferred backend logic
using XDG_CURRENT_DESKTOP still wins over this.
