Eliminate SIOCGIFADDR handling in bpf.

Browse Source 
Quoting 19 years bpf.4 manual from bpf-1.2a1:
"
(SIOCGIFADDR is obsolete under BSD systems.  SIOCGIFCONF should be
 used to query link-level addresses.)
"
* SIOCGIFADDR was not imported in NetBSD (bpf.c 1.36) and OpenBSD.
* Last bits (e.g. manpage claiming SIOCGIFADDR exists) was cleaned
  from NetBSD via kern/21513 5 years ago,
  from OpenBSD via documentation/6352 5 years ago.
