remove reference to overlay2 as a filesystem 

`overlay2` was incorrectly included as a filesystem that the `overlay` and `overlay2` storage drivers can't run on. `overlay2` is the name of the storage driver, but the filesystem is just called `overlay`. It was called `overlayfs` in older versions or the kernel, which would have helped disambiguate this, but I think we should continue to use `overlay` as the name of the filesystem because that's what the kernel uses now.
