fixes the desktop file:
* add -- to make cage ignore kodi's arguments
* add --standalone to kodi's arguments
update the dependencies:
* add upower as kodi tries to communicate with it to read battery status
* add pulseaudio as kodi complains it is missing
* add elogind as it is required for cage to run
* remove xorg-server
Fixes#469
The openrc service of lightdm has been moved to lightdm-openrc in
Alpine. Fix all UIs depending on lightdm, so their post-install script
does not fail with:
Executing postmarketos-ui-plasma-mobile-2-r6.post-install
* rc-update: service `lightdm' does not exist
