net.c: Remove compat macros for AI_V4MAPPED et al.

These were added 11 years ago during NetBSD-3.1 days because this
version of NetBSD lacked the three macros. At least on NetBSD-7.1
(released 2017), the compat macros are no longer necessary while
FreeBSD and Linux never needed them. So let's get rid of them.
