[PATCH] builtin-shortlog.c: use string_list_append() instead of duplicating its code

["Adeodato Simó" <dato@net.com.org.es>]

Also, when clearing the "onelines" string lists, do not free the "util"
member: with string_list_append() is not initialized to any value (and
was being initialized to NULL previously anyway).

NB: The duplicated code in builtin-shortlog.c predated the appearance of
string_list_append().
