ci: Add a migration compatibility test job

The migration tests have support for being passed two QEMU binaries to
test migration compatibility.

Add a CI job that builds the lastest release of QEMU and another job
that uses that version plus an already present build of the current
version and run the migration tests with the two, both as source and
destination. I.e.:

 old QEMU (n-1) -> current QEMU (development tree)
 current QEMU (development tree) -> old QEMU (n-1)

The purpose of this CI job is to ensure the code we're about to merge
will not cause a migration compatibility problem when migrating the
next release (which will contain that code) to/from the previous
release.

The version of migration-test used will be the one matching the older
QEMU. That way we can avoid special-casing new tests that wouldn't be
compatible with the older QEMU.

Note: for user forks, the version tags need to be pushed to gitlab
otherwise it won't be able to checkout a different version.
