Fix invalid .sha1 files for audio_coding

It seems like multiple runs of the upload_to_google_storage.py
script created .sha1.sha1 files that sneaked in with
https://code.google.com/p/webrtc/source/detail?r=5076

This caused the wrong files getting downloaded during sync.
This affected the modules_unittests and the neteq_unittests
which started failing (due to wrong version of the resource files).
