Add -j $JOBS to the CMake invocations missing it

Also addressing some linting changes

This will trigger a big rebuild, we should run the Cache Jenkins job on merge

Maybe we could link this to some useful update, like bumping fmt or a newer version of ninja?

[singiamtel]

Good idea, I'll try to bump as many as possible

• ninja: no update
• fmt: compilation error
• catch2
• faircmakemodules: no update

fmt error:

/sw/slc9_x86-64/fmt/11.0.2-local1/include/fmt/base.h:1402:29: error: passing 'const fmt::v11::formatter<o2::header::Descriptor<16>, char, void>' as 'this' argument discards qualifiers [-fpermissive]

I think you can remove this completely and simply use alibuild-generate-module (see other places)
