Release notes:
https://lists.infradead.org/pipermail/linux-mtd/2024-March/104058.html
mtd-utils are currently depending on zlib, however it is not expressed
as a dependency and it is somehow being only pulled-in by lincurses-devel
so mtd-utils were able to compile.
Since 2.2.0 zlib is optional so lets disable support for it like for other
compressors since we dont package the mkfs.ubifs or mkfs.jffs2 that
are only users of compressors anyway.
