Matthew Bauer 0a996c8ef3 darwin: use llvm’s dsymutil instead of dummy version
We were previously using a dummy wrapper for dsymutil. This meant that
debug symbols were not getting generated when dsymutil was otherwise
available. This should fix that issue & provide a real dsymutil from
llvm.

Fixes #52148.
