Add fallback to uncompress dax.ko.zst and dm-mod.ko.zst and insmod this in the t2 disk_hook.sh, as the default busybox modprobe/insmod doesn't support zstd modules.

T2 Linux uses zstd compressed kernel modules, where dm-mod also depends on the dax module, since recent kernel versions. So the default fallback to only decompress dm-mod isn't sufficient.

To boot this ISO e.g: t2-25.1-x86-64-base-wayland-glibc-gcc-nocona.iso

T2 uses zstd compressed kernel modules, where dm-mod also depends on
dax module. So the default fallback to only decompress dm-mod isn't
sufficient. So we manually uncompress dax.ko and dm-mod.ko and insmod
this, as default busybox modprobe/insmod doesn't support zstd modules.
