key_manager: Make use of IOFile in WriteKeyToFile()

This properly handles unicode-based paths on Windows, while opening a
raw stream doesn't out-of-the-box.

Prevents file creation from potentially failing on Windows PCs that make
use of unicode characters in their save paths (e.g. writing to a user's
AppData folder, where the user has a name with non-ASCII characters).
