[PATCH RFC] tests/migration-test: Add mapped-ram + ignore-shared test

[Peter Xu <peterx@redhat.com>]

It was broken, add a test for it.

NOTE: here we do not really need any shared memory blocks, enabling of both
of the features alone would cover the ramblock layout difference that the
bug triggers.

RFC because currently master branch is broken with it, so need to merge
only after a proper fix lands.

Pawel, feel free to take this with your fix when repost, or I'll manage.
