[yocto] [PATCH V4 10/10] update_layer.py: delete layerbranch for non-existed branch

[Robert Yang]

The branch is not needed any more when it has been removed from the repo, so we
also need remove its layerbranch, otherwise it still can be got from the web,
which causes confusions.

Note, we have to move the location of tinfiol's code to make it can be shutdown
correctly.
