import _binary_replace for win_file.py

Windows file management re-uses a lot of functions from
salt.modules.file, and a new function added in b93c724, which is needed
in check_file_meta(), was not added to the functions that are imported
into win_file.py. Fixes #6116.
Merge pull request #6120 from terminalmage/issue6116
