Removed the legacy Time Machine backup feature

I didn't ever use the feature but my understanding was it was for connecting a hard drive to the router and using the hard drive as a time machine backup. Don't quote me on that as I'm not an apple guy (even slightly). 

So if you have an actual time machine/capsule (?) that is hardwired in via ethernet, you should be fine. 

Worse case, make a backup and if it causes issues, you can always downgrade.
