For https://github.com/microsoft/go-winio/issues/311

This PR fixes memory alignment for the structs passed to both GetFileInformationByHandleEx and SetFileInformationByHandle.

Includes a direct test for memory alignment. (Also makes sure it has the right amount of padding, since it's convenient to check this in the test too.)
