Brightness, Inhibit: mark both applets incompatable with wayland

[lukefromdc]

*Brightness applet depends on Xrandr, and wlr-randr wayland equivalent does not yet offer brightness control
*Inhibit applet depends on Xevent and on x11 extension DPMS (X Display Power Management Signaling)

[lukefromdc]

These dependencies are in mate-power-manager itself not the applets: they can be ported to out of process and will then show in Wayland but mate-power-manager cannot be run. A "stripped" version of m-p-m for Wayland could probably be written to handle shutting down or suspending a laptop, and connect to an SNI replacement for the current status icon.

Travis build failure on Debian looks like a translation issue:
/usr/bin/msgfmt: cannot locate ITS rules for org.mate.power.policy.in

Only debian:testing failed to build. Fedora:latest (stable fedora 38) runs well and doesn't stop building at same place https://app.travis-ci.com/github/mate-desktop/mate-power-manager/jobs/608068767#L2042
I am guessing there is something wrong in debian:testing which can happen all the time; ...it's called testing, or something new unstable is introduced.
I will do a scratch build for fedora rawhide branch at fedora build-server (koji) to see if something new is introduced in linux world :-)

Building this branch for forthcoming fedora 39 or fedora rawhide works well.

So i guess it's a temporarily issue with debian-testing.

LGTM,
applets are not selectable in add-to-panel-dialog in wayland-session
