netfilter: conntrack: udp: set stream timeout to 2 minutes
We have no explicit signal when a UDP stream has terminated, peers just stop sending. For suspected stream connections a timeout of two minutes is sane to keep NAT mapping alive a while longer. It matches tcp conntracks 'timewait' default timeout value. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

This extended timeout will be used in case there is an UDP stream
detected.
