Fix clazy CI job
The build_clazy_clang_tidy
CI job on GitLab was still using ci-suse-qt514
,
for which we don't maintain dependencies in Jenkins anymore, so it failed
to build, saying it couldn't find any dependencies. Update it to use
ci-suse-qt515
.
This seems to fix the build, although it now fails because the code formatting doesn't match the output of clang-format. This will also cause errors on CI for merge requests, so maybe clang-format should be disabled for now?
