Bug Description
[Impact]
* To safe diskspace, upcoming devel series / hwe kernels may turn on zstd kernel module compression. Kmod since impish support zstd support. But in order to keep hwe kernels at parity, or allow inspecting jammy modules from focal host, it would be beneficial for kmod in focal to support zstd compressed modules.
[Test Plan]
* Pick any kernel module
* Compress it with zstd: $ zstd *.ko
* Check that modinfo can read it: $ modinfo *.ko.zst
[Where problems could occur]
* kmod will gain a new dependecy on libzstd1, however it should already be present, because dpkg in focal depends on libzstd1 already.
* initramfs-tools already supports compressed modules, but in focal at the moment it does so in an inefficient manner (regresses bootspeed), this has been improved in https:/
