tests: Log messages to stdout instead of stderr

* tests/run_parallel.h (run_parallel): Print logging (non-error)
messages using printf() instead of fprintf(stderr).
* tests/test_atomic_include.template (MISSING): Likewise.
* tests/test_malloc.c (print_list): Likewise.
* tests/run_parallel.h (run_parallel): Reformat code.
