QNetworkInterface - fix iOS/tvOS/watchOS builds

netinet/in_var.h, netinet6/in6_var.h, and  net/if_media.h are missing
in iPhoneOS.sdk(s). We only use several macros and data-structs from
these headers, so to work-around the broken build we provide the
missing definitionis.

Task-number: QTBUG-64447
Change-Id: I1b8169c12b4f33959f949bbf29e80f639ab31ad3
