[ptxdist] [PATCH v2] rules: host-erofs-utils: package

[Leonard Göhrs]

Erofs is a read only filesystem, much like squashfs, that is optimized
for read performance (rather than e.g. maximum compression ratio).

The erofs-utils host package allows building erofs images.
Since genimage does not have erofs support yet (there is a pull request
though [1]) this can for example be achieved via the tar input feature:

    $ mkfs.erofs -z zstd --ungzip --tar root.erofs root.tgz

and a custom rule.
