shortlog: fix wrapping lines of wraplen

A recent commit [1] fixed a off-by-one wrapping error.  As a
side-effect, the conditional in add_wrapped_shortlog_msg() to decide
whether to append a newline needs to be removed.  The function
should always append a newline, which was the case before the
off-by-one fix, because strbuf_add_wrapped_text() never returns a
value of wraplen; when it returns wraplen, the string does not end
with a newline, so this caller needs to add one anyway.

    wrapping of text
