fix_stack_using_bpsyms.py locates a .sym file based on file name only, not uuid or full path,
which causes a failure if a duplicate leaf file name is introduced. This patch introduces a
small utility program on mac and linux to extract a breakpad guid from a shared library or
executable to identify the correct symbol file when this ambiguity occurs. A subsequent commit
implements this for windows.
