bitbake: toaster: update checksettings command for auto-detection

We enhance the checksettings command to try to automatically
detect settings for running on localhost.

The checksettings will look for a nearby poky layer source,
for a nearby build directory, and will try to import settings
from "toasterconf.json" files found in the local layer.

On new configuration, it will also perform updates from the
layer source.
