Don't save file transfers in elevated contexts.

On Windows, impersonate the logged-in user (if any) before writing
the file, aborting if impersonation fails, such as if at the log-in
screen where there's no logged-in user.

On MacOS, abort the transfer if running as root, which signifies that
the host is running on the log-in screen.

Note that this will not prevent uploads on the lock screen, as the OS
still considers the user to be logged in, in that case.
