lib: fix log target removal when singlethreaded

While running singlethreaded, the RCU code is "dormant" and rcu_free is
an immediate operation.  This results in the log target loop accessing
free'd memory if a log target removes itself while a message is printed
(which is likely to happen on e.g. error conditions.)

Just use frr_each_safe to avoid this issue.
