Subject: [PATCH] extensions: time: Avoid undefined shift
Value 1 is signed by default and left-shifting by 31 is undefined for
those. Fix this by marking the value as unsigned.
Fixes: ad326ef9f734a ("Add the libxt_time iptables match")
(cherry picked from commit 98b221002960040bf3505811c06025b6b9b6984b)
