[PATCH 5/5] selftest/bblayers: add a test for creating a layer setup and using it to restore the layers

[Alexander Kanavin <alex.kanavin@gmail.com>]

This does a basic run-through of the bitbake-layers plugin, and the resulting json layer config
and the layer setup script that uses it. Only poky is actually fetched by the script.
