Victor Julien 1e836be3d8 output-lua: add SCLogPath callback
Add a lua callback for getting Suricata's log path, so that lua scripts
can easily get the logging directory Suricata uses.

Update the Setup logic to register callbacks before the scripts 'setup'
is called.

Example:

    name = "fast_lua.log"
    function setup (args)
        filename = SCLogPath() .. "/" .. name
        file = assert(io.open(filename, "a"))
    end
