fix: 'Manually' randomize feh wallpapers

The wallpaper folder is now in git and feh will pick any random file in
the folder that it is pointed at, leading to it constantly failing while
trying to set git objects as the wallpaper.

This uses  manual 'fd | shuf | xargs' pipeline for the same purpose.
