Include inotifytools in base OS

[Squid]

Due to the pervasiveness of inotifytools currently being required by multiple plugins (and probably more to come), and its relatively small size, it would probably be a good idea to include it going forward in the base OS. 

 

And it would save dmacias from continually having to update nerd pack with every release of unRaid just to keep the plugins that require inotifytools to remain functional.
