// modeType returns the mode type of the file system entry identified by
// osPathname by calling os.LStat function, to intentionally not follow symbolic
// links.
//
// Even though os.LStat provides all file mode bits, we want to ensure same
// values returned to caller regardless of whether we obtained file mode bits
// from syscall or stat call.  Therefore mask out the additional file mode bits
// that are provided by stat but not by the syscall, so users can rely on their
// values.
