After the change to use --setscene-only when running bitbake to prepare
the SDK at the end of installation, add a check that the SDK got
prepared correctly by doing a dry-run and looking at the output for any
real tasks that we don't expect. In order to make this easier, the
preparation shell script was rewritten in python.
