[PATCH 2/2] testsuite: Allow to enable sstate globally

[Uladzimir Bely <ubely@ilbers.de>]

By default, sstate cache is populated only, but not used during
the build (since `--no-setscene` bitbake param is passed by default).

Add `-S` (`--sstate`) option to ci_build.sh script in order to change
the default behaviour and allow sharing sstate cache between tests.
