Switch to afb-helpers library

Remove old afb-helpers submodule usage in favor of library from the
toolchain. Note that json.hpp is no longer shipped with the library,
and is now assumed to be present in the toolchain, which requires a
DEPENDS addition in the recipe to pick it up, and an #include of
sstream to work with newer versions of json.hpp.
