cilium: ipsec, wildcard out rules and remove localhost rules

Currently, OUT xfrm rules use full (src,dst,spi) tuple. The original
thinking on this was that we wanted to ensure matches only on relavent
IP addresses. However now both state and policy are further restricted
by mark values we can drop the src piece without worrying about having
unintended matches.
