aarch64 support

https://bugzilla.suse.com/show_bug.cgi?id=1221655

I checked on my RPi4:

• [x] gfx-boot theme is a broken dependency
• [x] pattern-sway-sway is a broken dependency
• [ ] waybar missing libwireplumber-0.4.so.0 lib
• [x] alacritty absent for aarch64 (foot works btw)
• [ ] as there some broken dependencies - many packages are not installed if ignore/break dependencies

so definitely there is some work to do to bring everything in order for aarch64.
