With respect to symlinks, the current `mingw_stat()` implementation is
almost identical to `mingw_lstat()`: except for the file type (`st_mode
& S_IFMT`), it returns information about the link rather than the target.
Implement `mingw_stat()` by opening the file handle requesting minimal
permissions, and then calling `GetFileInformationByHandle()` on it. This
way, all links are resolved by the Windows file system layer.
