gitlab-ci: allow failure of clang LTO pipelines
Required for [1].
The core problem is that the dwarves tool doesn't support some debuginfo constructs that are emitted by LLVM. As long as this is true, we are always at risk of a similar build failure happening even with the default gcc + rust build. A small change to the rust compiler or a new version of LLVM code easily change the debuginfo emitted by rust and cause this issue to reappear.
