Subject: [PATCH 19/26] BUILD: tcp: do not include netinet/ip.h for IP_TTL

On OpenBSD, netinet/ip.h fails unless in_systm.h is included. This
include was added by the silent-drop feature introduced with commit
2d392c2 ("MEDIUM: tcp: add new tcp action "silent-drop"") in 1.6-dev6,
but we don't need it, IP_TTL is defined in netinet/in.h, so let's drop
this useless include.

This fix needs to be backported to 1.6.
(cherry picked from commit 7f3e3c0159401cdf47575bc82304696b3a98a2ab)
