build: let 'make clean' remove logs/ again

Before in the recursive automake setting, we had tests/logs/ for
explicitly created test log files. There is a Makefile rule to
remove the logs directory on 'make clean'. The rule broke on moving to
non-recursive make, since now we have logs/, not tests/logs/.

Fix the rule to remove the intended directory.
