Ensure FC15 boots when zfs isn't used for boot partition

It seems that dracut version 009 through 013 won't boot correctly when
the zfs-dracut rpm package has been installed, but 'root=zfs' isn't
used on the boot commandline, for example when the package has been
installed on a system that _doesn't_ boot from a zfs filesystem.
