Add a NULL value in the end of STRING_LIST_INIT_NODUP and
STRING_LIST_DUP to initialize `compare_strings_fn`.

When I used a malloced string_list to play around with string-list API and
used the default init_list, it caused a seg fault. After an hour of debugging
I saw that comapre_strings_fn should be initialized to NULL. In C, even an
incomplete initialzer initializes every value to NULl or 0, so in normal
usage in the codebase this problem never occurs. Still it is better to be
thorough.
