suse-migration-services-2.1.23-160000.1.1

- Activation packages can no longer be noarch
  As we have architectures that does not support the grub
  based activation and therefore an ExclusiveArch setup in
  the spec, the package can no longer be noarch

- Bump version: 2.1.22 → 2.1.23

- Bump Migration changelog version: 2.1.23

- Fix update of image .changes files
  We want a new entry with each version change but
  bumpversion modifies the existing version changelog
  entries which is unwanted. Thus the .changes files
  got dropped from .bumpversion.cfg and a little
  helper tool to handle the .changes entry was added
  and called through the Makefile

- Bump version: 2.1.21 → 2.1.22

- architecture check before allowing migration to be activated
  SLE16 will panic on CPUs older than x86_64_v1 (i.e. x86_64). To
  avoid panicing the system we check for the architecture before
  activating the migration.
