exec: proc_exec_connector() should be called only once
A separate one-liner with the minor fix. PROC_EVENT_EXEC reports the "exec" event, but this message is sent at least twice if search_binary_handler() is called by ->load_binary() recursively, say, load_script(). Move it to exec_binprm(), this is "depth == 0" code too.
