Andrew Leech a2703649ea tools/pydfu: Workaround stdio flush error on Windows with Python 3.6.
There appears to be an issue on Windows with CPython >= 3.6,
sys.stdout.flush() raises an exception:

    OSError: [WinError 87] The parameter is incorrect

It works fine to just catch and ignore the error on the flush line.  Tested
on Windows 10 x64 1803 (Build 17134.228), Python 3.6.4 amd64.
