Fix extracted files permissions

[gilfree]

Fix #608: This commit fixes the extracted file permissions when using .extract/.extract_files in addition
to when using the unpack cli command.

The fix is by overriding the _extract_member method of zip file, and adding permissions fix there.

The permissions fix was moved from the unpack to the new method.

Any plans to merge this? Anything I can do?

In what situation would this change ever be used? The WheelFile class in this library is not part of any public API.

Ok, then. Your choice, I just thought you wanted this change, will close this PR.

Thanks for your work :)

Yeah, sorry, this was a brain fart of mine. First I OK'd this PR, then I turned it down. I guess I was just too busy with everything else and got confused, especially given how much time had passed. I don't know why I initially thought there would be a point in making the change to WheelFile itself at this point. If this change is to be made to a wheel API, it should be made to a public API, like the one I've been working on here.
