Log: Fix os.getexecpath() (code and tests) for python -bb Catch BytesWarning exceptions.

You should not catch warnings, but silence them using constructs provided by the warnings module:

with warnings.catch_warnings():
    warnings.simplefilter(ignore, BytesWarning)
    # the rest of your code

Otherwise you'll get buggy behaviour where e.g. env[b'PATH'] raises BytesWarning because of an unicode key, but it would have succeeded otherwise.

Regards

Antoine.
