[PATCH 1/2] libtracefs: Silence non-literal-null-conversion warning

[Ian Rogers <irogers@xxxxxxxxxx>]

On clang the warning looks like:

src/tracefs-utils.c:473:15: error: expression which evaluates to zero treated as a null pointer constant of type 'char *' [-Werror,-Wnon-literal-null-conversion]
        list[size] = '\0';
