features: support zfs 2.2.x
ZFS has merged all but the spl kernel module into the zfs module
https://github.com/openzfs/zfs/commit/ad9e767657c3d3c0ec9e09a17f6732bcbf915401
These two modules now appear as
/lib/modules/<kver-flavor>/extra/spl.ko.gz
/lib/modules/<kver-flavor>/extra/zfs.ko.gz
Previously
/lib/modules/<kver-flavor>/extra/spl/spl.ko.gz
/lib/modules/<kver-flavor>/extra/zfs/zfs.ko.gz
...
This change allows for both pre and post ZFS 2.2.x kmod installations.
