Fix zfs-kmod builds when using rpm >= 4.14

Fix zfs-kmod builds when using rpm >= 4.14

With rpm-software-management/rpm@5e94633 a package version containing
invalid characters (most commonly a double '-') causes the kmod package
generation to terminate with an error.  This change takes advantage of
the newly introduced rpm macro "_wrong_version_format_terminate_build"
to allow kmod packages to be built.
