[cmake] Add llvm-debuginfod as test dependency

[luke]

Summary

llvm-debuginfod is used by llvm-lit as of
36f01909a0e29c1014301ed6835687a84bf0e9fa, so adding this dependency
fixes a "note: Did not find llvm-debuginfod" warning from showing up
when running tests.

Thanks, this LGTM. I see the comment mentions updating "test/lit.cfg" as well -- do you think this means llvm/test/lit.cfg.py? If so, we've already added the substitution there so we should be good.

Yeah I believe so!
