    main: remove default values for other-module parameters in snort module

    Snort module is not listed in coreinit.lua as a builtin module,
    thus some of its parameters get their default values elsewhere.

    Adjust the range for snaplen parameter, as in daq.

    Update --daq-batch-size description with a default value.

    Lowest: targeted module config entry (from Lua)
