board_status.sh: Be smarter about cbfstool usage

This changes how we build and use cbfstool:
1. If build/cbfstool exists, use it.
2. Otherwise, try util/cbfstool/cbfstool.
3. As a last resort, build it and clean it when we're done.

Hopefully this will resolve issues people have had with permissions
and reduce overhead of building cbfstool when not necessary.
