Auto merge of #3408 - ad0:fanotify-new-constants, r=JohnTitor
feat: add new constants from fanotify linux api Since it's introduction in Linux and in this repo (#1699), several new features have been introduced in the fanotify API. In the original fanotify API, only a limited set of events was supported. In particular, there was no support for create, delete, and move events. The support for those events was added in Linux 5.1. This PR adds missing constants from `fanotify.h` to support the newest features.
