Make children tracking in execute_actions() more async-aware

We need to update the children count in children->nb
after starting each child process instead of after
starting all of them, because we use that count
in wait_for_children(), which is run asynchronously
for each child.

Fixes bug #3979: Hang (with killing needed) during
action which extracts attachments
