dracut: handle compressed kernel modules

[mikhailnov]

Compressed kernel modules could not be loaded. Now both compressed and not compressed ones will be loaded.

$ uname -r 5.10.74-generic-2rosa2021.1-x86_64 $ ls -1v /lib/modules/$(uname -r)/kernel/drivers/scsi/device_handler/ scsi_dh_alua.ko.zst scsi_dh_emc.ko.zst scsi_dh_hp_sw.ko.zst scsi_dh_rdac.ko.zst

Yes, it seems to work, at least it does not say that it failed to load kernel modules. I have not made iSCSI fully workable yet. For example, ROSA package of multipath-tools did not have mpathconf utility which is carried as a patch in the Fedora/RH package and does not exisf in upstream, Anaconda failed to start if multipath-tools was installed but mpathconf did not exist. Now it exists but python-blivet gets an error from udisks2, I will examine it a bit later.

Well, this bit should be helpful on its own, I think? I can't speak for the whole team but loading also compressed modules seems like an improvement, even if it's one step towards some goal.

@VladimirSlavik @mikhailnov is this PR ready to be merged? It seems to me like that.
