Allow --dump-dmesg for Xen vmcores

If a Xen dump is detected, makedumpfile checks that the target format is ELF. The real reason is that compressed formats are not possible with Xen.

But there's a third way initial_xen() can be called: with --dump-dmesg. This variant works in fact, so it's enough to extend the check so that it covers this case.
