inotify: completely ignore events on the repository root
They can only be events on the top directory object. Those events are
meaningless for us: permission changes, repository-wide moves...
And they break the assertion that all events happen in repo/*.
Just ignore them.
Fixes one of the failures of run-test.py --inotify test-permissions
