The strdup() function returns a pointer to a new string which is a duplicate of the string "ptr". Memory for the new string is obtained with malloc(), and need to be freed with free().

This patch adds these missing "free(ptr)" in check_whitelist() and check_blacklist() to avoid memory leaks in test_sockmap.c.
