For the gitlab custom-runners, drop to only --enable-ubsan. These jobs are not run by default, but as will be obvious in the next patch, we don't run ASan on x86 either, and it seems wrong to hold aarch64 and s390x to a different standard.

We must disable this for normal usage of --enable-ubsan as well, so move it there. Append options rather than prepend, since all of this requires proper ordering of options.
