meson: Enable ZFS storage backend more often

Currently, the ZFS storage backend is enabled only if both zfs
and zpool binaries were found during configure phase. This is not
consistent with our attempts to move dependencies on binaries
from compile to runtime. And also it is inconsistent with other
backends, e.g. vstorage.
