exclude: add flags parameter to add_patterns()

There are a number of callers of add_patterns() and its sibling functions. Let's give them a "flags" parameter for adding new options without having to touch each caller. We'll use this in a future patch to add O_NOFOLLOW support. But for now each caller just passes 0. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
