core: modernize execution code a bit
Among other things, avoid log_struct() unless we really need it. Also, use "r" as variable to store function errors in, instead of "err". "r" is pretty much what we use everywhere else, hence using the same here make sense. FInally, in the child, when we want to log, make sure to open the logging framework first, since it is explicitly closed in preparation for the exec().
