[LU-12745] Lustre fails to compile against zfs dkms 0.8+

Related — Thu, 21 Nov 2019 21:51:29 +0000

kmod-zfs-devel provides a vestigial spl directory for kmod base installs, so this issue is limited to zfs dkms based installs.

Because there's no spl directory, lustre configure fails enable zfs osd build.
