remote-curl: pass curl slot_results back through run_slot

Browse Source 
Some callers may want to know more than just the integer
error code we return. Let them optionally pass a
slot_results struct to fill in (or NULL if they do not
care). In either case we continue to return the integer
code.

We can also give probe_rpc the same treatment (since it
builds directly on run_slot).
