    linux-user: Use EPROTONOSUPPORT for unimplemented netlink protocols
    
    Linux uses the EPROTONOSUPPORT error code[1] if the users requests a
    netlink socket with an unsupported netlink protocol. This change
    switches linux-user to use the same code as Linux, instead of
    EPFNOSUPPORT (which AFAIK is just an anachronistic version of
    EAFNOSUPPORT).
    
    Tested by compiling all linux-user targets on x86.
