include: Avoid undefined left-shift in xt_sctp.h

Pull the fix in kernel commit 164166558aace ("netfilter: uapi: Avoid
undefined left-shift in xt_sctp.h") into iptables repository. The
original description is:

With 'bytes(__u32)' being 32, a left-shift of 31 may happen which is
undefined for the signed 32-bit value 1. Avoid this by declaring 1 as
unsigned.
