improve-hookfs

Function

• Add rename hook
  In prometheus tsdb, it needs this scene

• Use go module
  Use go-fuse 1.0, but interface of nodefs.File are changed

//implements nodefs,GetLk
func (h *hookFile) GetLk(owner uint64, lk *fuse.FileLock, flags uint32, out *fuse.FileLock) (code fuse.Status) {
	return h.file.GetLk(owner, lk, flags, out)
}

//implements nodefs.SetLk
func (h *hookFile) SetLk(owner uint64, lk *fuse.FileLock, flags uint32) (code fuse.Status) {
	return h.file.SetLk(owner, lk, flags)
}

//implements nodefs,SetLkw
func (h *hookFile) SetLkw(owner uint64, lk *fuse.FileLock, flags uint32) (code fuse.Status) {
	return h.file.SetLkw(owner, lk, flags)
}

• Support test case
  Actually, we do not need to unmount mountpoint by the manual way.
  We can unmount it by this way in test case

syscall.Unmount(mountpoint, -1) //of course, it also call fusermount command
