pretty: drop unused strbuf from parse_padding_placeholder()

Unlike other parts of the --pretty user-format expansion, this function is not actually writing to the output, but instead just storing the padding values into a context struct. We don't need to be passed a strbuf at all. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
