extensions: libxt_TEE: Trim kernel struct to allow deletion
Correct trimming of userspacesize to fix deletions.
Fixes: Bugzilla #884.
The rule having TEE target with '--oif' option cannot be deleted by iptables command.
$ iptables -I INPUT -i foo -j TEE --gateway x.x.x.x --oif bar
$ iptables -D INPUT -i foo -j TEE --gateway x.x.x.x --oif bar
iptables: No chain/target/match by that name.
