    selftests/bpf: Fix endianness issue in sk_assign
    
    [ Upstream commit b6ed6cf4a3acdeab9aed8e0a524850761ec9b152 ]
    
    server_map's value size is 8, but the test tries to put an int there.
    This sort of works on x86 (unless followed by non-0), but hard fails on
    s390.
    
    Fix by using __s64 instead of int.
