Add a means of extending the dependency extraction for autotools and
cmake.
Note: in order to have this work, you need to have an __init__.py in the
lib/recipetool directory within your layer along with the module
implementing the handlers, and the __init__.py needs to contain:
# Enable other layers to have modules in the same named directory
from pkgutil import extend_path
__path__ = extend_path(__path__, __name__)
