libnetfilter-log: Backport kernel header syncs

Browse Source 
Backport upstream commits that sync the local kernel header
copies in this library, with up to date copies.  These updated
headers ensure that libnetfilter-log users can use current
kernel functionality such as requesting that conntrack
information be appended to nflog events sent to userspace via
the NFULNL_CFG_F_CONNTRACK flag.  This functionality has been
available since kernel version 4.4
