strbuf: retire strbuf_commented_addf()

The API allows the caller to pass any string as the comment prefix,
but in reality, everybody passes the comment_line_str from the
environment.

Replace this overly flexible API with strbuf_comment_addf() that
does not allow customization of the comment_line_str (usually '#'
but can be configured via the core.commentChar).
