    building(linux): include <netinet/in.h> _before_ kernel headers like xfrm.h
    
    Linux include headers define sockaddr_in both in:
    
       <netinet/in.h> - GLIBC or MUSL C library
       <linux/in.h> - the Linux kernel header
    
    (ditto for sockaddr_in6) which means that including both will result
    in a clash.
    
    Fortunately, hacks have been added to avoid this.  Specifically, both
    GLIBC and MUSL define macros that stop the Linux kernel headers
    (notably <linux/xfrm.h>) from including <linux/in.h> when
    <netinet/in.h> has already been included.  Hence this change to always
    include <netinet/in.h> first.
    
    (GLIBC also has hacks handle to handle the reverse case, but not
    MUSL).
