[PATCH] scripts/dtc: Add missing fdtoverlay to gitignore

[Rob Herring]

Commit 0da6bcd9fcc0 ("scripts: dtc: Build fdtoverlay tool") enabled
building fdtoverlay, but failed to add it to .gitignore.

Also add a note to keep hostprogs in sync with .gitignore.

Linus, please pick this up directly if you want. I'm going to be offline
most of the next couple of days, will have a few other DT fixes to send 
you later this week.
