[yocto-autobuilder-helper][PATCH] config.json: Enable dedicated sstate during build and remove after

[Michael Halstead <mhalstead@linuxfoundation.org>]

Without any sstate available oe-selftest cannot run in parallel. Set sstate to a
location used only by these builds and remove it as the last step.
