[PATCH v2 16/17] testsuite: make sbuild-flavor test standalone

["'Felix Moessbauer' via isar-users" <isar-users@googlegroups.com>]

As the hello-isar recipe acts as an example for the SBUILD_FLAVOR
feature, we also pull in a dedicated chroot into almost all tests. This
is very costly and does not add much value. We change this by setting
the SBUILD_FLAVOR of hello-isar to none in the CI layer and add a
dedicated test that just tests the SBUILD_FLAVOR feature.

This only slightly reduces the test coverage, but it significantly
speeds up the test execution.
