Adjust tests for MacOS having different -Csplit-debuginfo default

MacOS (and all apple targets) have -Csplit-debuginfo=packed as default
instead of "off" like all other targets (well there is Windows, but we
don't test it in those tests), also -Csplit-debuginfo is not stable on
all targets so we only set in on Darwin where is matters.
