Remove _witherspoon from remaining bbappend files

9c653e0df was the first commit in this direction.

These files are already in the meta-witherspoon subdirectory, it's
redundant to have the _witherspoon append in the bbappend files.

This allows off-shoots of the witherspoon system to easily include this
meta layer and get the witherspoon default files.
