Check if all device packages have the same arch in their device
APKBUILD as they have in their deviceinfo. And that they have
!archcheck set in the options.
This test case only makes sense in the pmbootstrap repository, and
we have it there already. In pmaports, we don't need to check if the
"aportgen" code is working - and to check the versions of the aports
we already have the test_upstream_compatibility case.
Copy all test cases from the pmbootstrap repository, that are actually
testing the aports. They were all adjusted to work nicely in this
repository, together with a brand new set of gitlab-ci configs.
This also includes the changes from this merge request, that had a
better detection of changed packages:
