Fix NSE error: attempt to get length of a number

Browse Source 
NSE: Script Engine Scan Aborted.
An error was thrown by the engine: attempt to get length of a number
value
stack traceback:
        [C]: in function 'port_set_output'
        /home/rt/builds/nmap/nse_main.lua:314: in function 'set_output'
        /home/rt/builds/nmap/nse_main.lua:947: in function 'run'

</home/rt/builds/nmap/nse_main.lua:1237>
        [C]: in ?

This now allows return of anything stringifiable as second return value
without crashing (though this may not be what the script author intends,
better to not crash)
