fs-tests: integck: clean-up copy_string
This is a clean-up patch which: 1. Simplifies copy_string by useng strdup instead of malloc 2. Adds an assertion which checks the input parameter agains NULL, instead of checking it. 3. Re-names it to dup_string which looks more readable to me. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
