Fixes the following warnings:
dirty_log_test.c: In function ‘help’:
dirty_log_test.c:216:9: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 2 has type ‘int’ [-Wformat=]
printf(" -i: specify iteration counts (default: %"PRIu64")\n",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from include/test_util.h:18:0,
from dirty_log_test.c:16:
/usr/include/inttypes.h:105:34: note: format string is defined here
# define PRIu64 __PRI64_PREFIX "u"
dirty_log_test.c:218:9: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 2 has type ‘int’ [-Wformat=]
printf(" -I: specify interval in ms (default: %"PRIu64" ms)\n",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

/usr/include/inttypes.h:105:34: note: format string is defined here
