fix(libkernel): unlink a dangling Windows directory symbolic link

Browse Source 
sceKernelUnlink takes its Windows directory-link path only when
std::filesystem::symlink_status reports a directory, but MinGW's
symlink_status follows the link. A directory symbolic link whose target
is missing therefore looked like a file, went to the file delete, and
failed with EACCES, because Windows removes a directory link only
through RemoveDirectoryW. guest_filesystem stops there on any Windows
host that may create symbolic links.

The directory path is now also taken when the link itself carries both
FILE_ATTRIBUTE_DIRECTORY and FILE_ATTRIBUTE_REPARSE_POINT, which
GetFileAttributesW reports without following the link.
