SDDM Astronaut theme with Autologin

This script installs sddm-astronaut-theme from last stream and provides an option to enable autologin with sddm. Users can choose which desktop session they want to autologin on startup. After selecting desktop session, it will do a sddm restart and autologin to that desktop.

Testing

If you want to test it first, do the following.

git clone --branch sddm https://github.com/mashrukk/linutil
cd linutil && cargo run

@mashrukk You'll have to revert these 3 commits, too many breaking changes in them. After that move these to the bottom of the script

@nnyyxxxx I reverted the changes. I have an exam tomorrow. Can you please fix the issues and share the updated version? That'd be great.
