transport-helper: plug strbuf and string_list leaks
Transfer ownership of detached strbufs to string_lists of the
duplicating variety by calling string_list_append_nodup() instead of
string_list_append() to avoid duplicating and then leaking the buffer.
While at it make sure to release the string_list when done;
push_refs_with_export() already does that.
