[Xen-devel] [PATCH OSSTEST] Do not attempt migration tests if the platform doesn't support it

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Doing so blocks the rest of the tests in the job, which may be able to
indepentently complete. So arrange for a ts-migrate-support-check test to run
and gate the remaining migration tests on that.

This relies on the xen patch "xl: suppress suspend/resume functions on
platforms which do not support it" to actually suppress migration support on
arm.

This needs to go in after the Xen patch. Otherwise this new step will appear to
pass and then start to fail when the Xen patch is applied.
