fix a format string issue in array test

ARRAYLIST_IDX deals with the head pointer. Explicitly cast to unsigned long
and use %lu in the format string.

Clang 10.0.1 used to complain as follows:

arraylist_test.c:19:2: warning: format specifies type 'int' but the
argument has type 'long' [-Wformat]
arraylist_test.c:15:24: note: expanded from macro 'dump' 
printf("[%d] %d\n", ARRAYLIST_IDX(p, list), *p); \
~~         ^~~~~~~~~~~~~~~~~~~~~~
