Allow cleanup of incomplete component registration.

If ImageLoader crashes, for example due to a seccomp filter violation,
it can leave an incomplete installation on disk that will block a valid
installation from occurring in the future. This makes sure ImageLoader
cleans up any junk left behind from a crash.
