test-string-list.c: Fix some sparse warnings

In particular, sparse complains as follows:

        SP test-string-list.c
    test-string-list.c:10:6: warning: symbol 'parse_string_list' was not \
        declared. Should it be static?
    test-string-list.c:18:6: warning: symbol 'write_list' was not \
        declared. Should it be static?
    test-string-list.c:25:6: warning: symbol 'write_list_compact' was not \
        declared. Should it be static?
    test-string-list.c:38:5: warning: symbol 'prefix_cb' was not \
        declared. Should it be static?

In order to suppress the warnings, since the above symbols do not
need more than file scope, we simply include the static modifier
in their declaration.
