bitbake: cooker: Further fixes to inotify to fix memres bitbake issues

The previous fix for inotify wasn't quite correct as we need to modify
bbseen before calling add_filewatch(). We also need to ensure the parse
mtime cache is cleared when directories are added/removed. There was also
a typo in the original fix and the wrong watcher was being changed. Fix
the various issues which improves memory resident bitbake testing results.
