GitLab disabled downloads of tarballs currently, because it was being
exploited for DoS agains their infrastructure. Work around this by using
git clone for now. I've thought about using --depth=1, but that would
break the ability to choose different branches.

When we bump the version in pmaports.cfg and the min. required pmaports
version in the pmbootstrap code, then forks of pmaports.git must be
rebased on pmaports.git master. Otherwise "pmbootstrap init" fails, and
because we have it set to quiet (so the output does not distract from
the interesting output if everything goes fine), there was no meaningful
error message yet.
Wrap the "pmbootstrap init" call and display a helpful message that
tells the user to rebase.
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:
