    net-snmp: fix engineBoots value on SIGHUP
    
    Store the incremented engineBoots value on SIGHUP.
    And don't reset engineBoots to 1 when oldEngineIDLength is 0.
    For the first run, the oldEngineIDLength is 0.
    When we say first run of the daemon, we talk about the
    first run ever on the machine, not only first run of every boot.
