tests/valgrind: rename name of logfile for valgrind run

Change the name of the file where to store the results
of the valgrind run.

Previously the file had a prefix "valgrind-", which is inconvinient.
Instead, have the file using the same name as the test executable,
with a ".valgrind-log" suffix.
