[PATCH-next v2 16/18] lnst.RecipeCommon.Perf.Evaluators.BaselineEvaluator: fix return value type

From: Ondrej Lichtner <olichtne(a)redhat.com&gt;

The return value of compare_result_with_baseline should be a list of
strings that describe the comparison. The result gets used in the
evaluate_group_results method which joins all the lists together.

Returning a string here would still work becuase it can be iterated but
it would result in incorrect formatting of the result.
