Historically this was correct, because we only supported labels for
one security driver. When we added support for multiple security
drivers it seems we caused a regression.

<seclabel relabel="no"/>

should have been treated as equivalent to

<seclabel relabel="no" model="selinux"/>

but we're not doing that :-(

If you explicitly add the model it'll do what you want. We should
still fix this bug though
