[tor-commits] [tor-browser-bundle/master] Forcibly overwrite .pyc timestamps.

commit faa70d800950656a2e21600dd2a9225b645f7576

    Forcibly overwrite .pyc timestamps.
    
    For each extension module, py2exe generates and byte-compiles a tiny
    stub .py file that loads the module:
    
    creating python loader for extension 'bz2' (Z:\home\ubuntu\install\python\DLLs\bz2.pyd -> bz2.pyd)
    
    These .py stubs are dynamically generated at py2exe time, so we don't
    have an opportunity to set the mtime of .py files ahead of time. But we
    can set the .pyc timestamps after the fact.
    
    I believe this commit makes bd4b3de712e345adc20ec9e959759f03da5826bc
    superfluous, but I'm leaving that one because I hope there is a nicer
    way to do this one.
