    linux: Substitute linux/if.h with net/if.h
    
    There is an age-old conflict between linux/if.h (the kernel header) and
    net/if.h (the userland header) that leads to compile errors due to
    redeclaration of certain network-related structures, see e.g. the following links:
    
    - https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/673073
    - https://lists.debian.org/debian-kernel/2017/06/msg00003.html
    - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=824442
    
    FWIW, it still seems to be a very current problem which I just stumbled over _again_.
    By now all the relevant structures should have counterparts in net/if.h, so let's try
    to just not include the kernel header, but use the userland header instead.
