mingw: cope with the Isilon network file system
On certain network filesystems (currently encountered with Isilon, but in theory more network storage solutions could be causing the same issue), when the directory in question is missing, `raceproof_create_file()` fails with an `ERROR_INVALID_PARAMETER` instead of an `ERROR_PATH_NOT_FOUND`. Since it is highly unlikely that we produce such an error by mistake (the parameters we pass are fairly benign), we can be relatively certain that the directory is missing in this instance. So let's just translate that error automagically. This fixes https://github.com/git-for-windows/git/issues/1345.
