* server : add custom socket options to disable SO_REUSEPORT

Signed-off-by: Adrien Gallouët <angt@huggingface.co>

* Add --reuse-port

    $ strace -e trace=setsockopt,bind build/bin/llama-server -lv 2 --reuse-port
    setsockopt(3, SOL_TCP, TCP_NODELAY, [1], 4) = 0
    setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
    setsockopt(3, SOL_SOCKET, SO_REUSEPORT, [1], 4) = 0
    bind(3, {sa_family=AF_INET, sin_port=htons(8080), sin_addr=inet_addr("127.0.0.1")}, 16) = 0
