mate-screensaver: update to 1.22.1.
Switch from consolekit to elogind.

I disabled consolekit explicetly due to #ifdefs in gs-listener-dbus.c
No need to explicetly enable elogind in configure. Elogind ships a /usr/lib/pkgconfig/libsystemd.pc and a relevant simlinked include directory. Mate screen saver sources actually reuse the systemd #ifdef for elogind anyways.
This was tested by closing and opening laptop lid as well as "loginctl lock-session".

A patch file from https://github.com/void-linux/void-packages/pull/14599.patch is attached
