ci: use lld along with clang

This is a fix for linking errors with MSAN/UBSAN when static runtime is linked also into shared library, which causes weak symbols to me incorrectly referenced by bfd. Just use lld, which is clever about this case and we already force clang for those builds anyway.

@haasn Would it be possible to install lld in docker image? This linking error is stupid and annoying and we should use competent linker instead of selectively disabling things that doesn't build.

I'll submit an MR to https://code.videolan.org/videolan/docker-images

mentioned in commit haasn/docker-images@55020239

mentioned in merge request docker-images!240 (merged)

@kasper93 you can update the jammy CI image to registry.videolan.org/libplacebo-ubuntu-jammy:20230329001344 to make this work
