Set working dir for test run script + update resources
Set working dir for test run script + update resources

By changing the working directory for the executing script to the same
directory as the script is located in, it is possible to run the script
standing in a higher-level directory (otherwise the input file relative
paths become invalid).

This CL also changes the input file path for the audio_e2e_test test to
assume the file is located resources.

BUG=none
TEST=locally executed the tests standing in trunk/
