bitbake: toaster: add fields for sourcedir and builddir paths

We add explicit absolute paths for a directory where
the layer sources will be checked out (sourcedir) and
where the build activities will take place.

Adding minimal checking when starting the application in
order to make sure that BuildEnvironment (BE) settings are
usable. This check is ran by the toaster script at startup.

Modify the localhost bbcontroller to use the BE settings
instead of trying to self-configure on checked out sources.
