tests/kola: add autosave-xfs tests

Add a new `ext.config.root-reprovision.autosave-xfs` test that checks
that the logic kicks in on a large enough disk. Add a similar
`ext.config.root-reprovision.luks.autosave-xfs` for the LUKS version
of this.

Sanity-check in other reprovisioning tests that autosave-xfs didn't
kick in.
