Patch series "lib/tests: string_helpers: Slight improvements".

Two ad-hoc patches to improve the test module.  It was induced by another
patch that poorly tried to add (existing) test cases and make me revisit
string_helpers_kunit.c.


This patch (of 2):

Currently the escape and unescape test cases go in one step.  Decouple
them for the better granularity and understanding test coverage in the
results.
