Generate rpmtests.at automatically to avoid redundant book-keeping

We have the list of tests in cmake, we can just as well generate the
master rpmtests.at file from there.

As the order of tests now depends on the list in tests/CMakeLists.txt,
update it to match the former order in rpmtests.at. As arbitrary as
that order is, people seem to get attached to certain test numbers. Er.
