clean_header: Fix error handling for no-such-file case
The function cleanupFile should always return a single value (as opposed
to a tuple or list). In addition, if it encounters an error, it is
expected to return a value that evaluates to False. As it stands,
however, it returns (None, None) in certain error cases. Change this
function to return None, in those cases.
We previously saw the following error message, when we tried to run
clean_header.py on a non-existent file.
Traceback (most recent call last):
File "clean_header.py", line 208, in <module>

File "utils.py", line 164, in updateGitFiles

File "utils.py", line 136, in _writeFile
f.write(self.new_data[dst])
TypeError: expected a string or other character buffer object
