ObjectFileBreakpad breaks TestFunctionStarts on the MacOS bot

The ObjectFileBreakpad change (r348592) first got tested on the bot for:

http://lab.llvm.org:8080/green/view/LLDB/job/lldb-cmake/13712/

and immediately TestFunctionStarts started failing.

You probably didn't get a mail because the previous test run failed with one of these "concurrent signal" tests which seem to be unreliable.
