- add Zstandard compression support, allows to enable the
kernel CONFIG_MODULE_COMPRESS_ZSTD option
- LIBKMOD_ZLIB/ZSTD select HOST_LIBKMOD_ZLIB/ZSTD so depmod understands
compressed modules during kernel build
---
Changes since v1:
- fix alignment
- enable host-libkmod zlib support, selected by libkmod zlib support
