[mac] Modify Mac default timeout for TIME_WAIT

macOS has only 16K ports available that won't be released until socket

TIME_WAIT is passed. The default timeout for TIME_WAIT is 15 seconds.

Consider reducing in case of available port bottleneck.


You can check whether this is a problem with netstat:


    # sysctl net.inet.tcp.msl

    net.inet.tcp.msl: 15000


    # sudo sysctl -w net.inet.tcp.msl=1000

    net.inet.tcp.msl: 15000 -> 1000


Run siege.config to create the ~/.siegerc config file.
