postmarketos-ui-sway already depends on xorg-server-xwayland for
X clients. There is no need to pull in the entire X server including
all necessary drivers.
This saves ~84 MiB of disk space when installing postmarketos-ui-sway
on asus-me176c. X applications are still working fine through Xwayland.
Also remove explicit dependency on dbus - it is already pulled in
by dependencies like lightdm or elogind and nothing in
postmarketos-ui-sway depends on it specifically.
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
