This one is easy!  Add "join[,]" to the end of your filter, like this:

<$set name="myVariable" 
filter="[tag[IncomingItem]!has[date_received]has[tracking_number]get[tracking_number]join[,]]">
<a href={{{[<myVariable>addprefix[https://t.17track.net/en#nums=]]}}} 
>Track All</a>
</$set>

note: you don't actually need to use a variable at all.  Just combine the 
two filters, like this:
<a href=
{{{[tag[IncomingItem]!has[date_received]has[tracking_number]get[tracking_number]join[,]addprefix[https://t.17track.net/en#nums=]]}}}
 
>Track All</a>

also, you might want to add target="_blank" to your link, so that it opens 
in a separate tab/window.
<a target="_blank" href=
{{{[tag[IncomingItem]!has[date_received]has[tracking_number]get[tracking_number]join[,]addprefix[https://t.17track.net/en#nums=]]}}}
 
>Track All</a>

enjoy,
