Add support for erofs

[schaefi]

erofs is an alternative readonly filesystem that can be used as alternative to squashfs. This Fixes #2633

Please find an integration test build here:

I'd also like a Rawhide test for this with both live image and filesystem image since these are going to be actively used.

What do you mean by "filesystem image" ? a simple filesystem image ? not bootable just for mounting ?

Yes, @davide125 is making a FEX rootfs image with kiwi and wants to use erofs for it (and there's general talk of making container images using erofs), so I'd like for us to make sure this works.

ok, I will add those integration tests once the one I have works
