mingw: suggest windows.appendAtomically in more cases

When running Git for Windows on a remote APFS filesystem, it would
appear that the `mingw_open_append()`/`write()` combination would fail
almost exactly like on some CIFS-mounted shares as had been reported in
#2753, albeit with a
different `errno` value.

Let's handle that `errno` value just the same, by suggesting to set
`windows.appendAtomically=false`.
