Bjoern A. Zeeb b25d74e06c Improve ARP logging. 
r344504 added an extra ARP_LOG() call in case of an if_output() failure.
It turns out IPv4 can be noisy. In order to not spam the console by default:
(a) add a counter for these events so people can keep better track of how
    often it happens, and
(b) add a sysctl to select the default ARP_LOG log level and set it to
    INFO avoiding the one (the new) DEBUG level by default.

Claim a spare (1st one after 10 years since the stats were added) in order
to not break netstat from FreeBSD 12->13 updates in the future.
