Update to the new location of the generate_breakpad_symbols.py script.

Update to the new location of the generate_breakpad_symbols.py script.

This script will be moved by
https://codereview.chromium.org/1315303004/ when it re-lands. Update to
the new location in dump_reader_multipart.py, and temporarily disable
the check_breakpad_symbols_actually_exists test to keep the bots green.
