net/arp: Give the unit of the ARP entry ages as 10 seconds.
The code converts CONFIG_NET_ARP_MAXAGE and
CONFIG_NET_ARP_MAXAGE_UNREACHABLE with SEC2TICK(10 * value): the unit
is 10 seconds. The help texts said deciseconds, and the comment in
netconfig.h said tenths of seconds, 100 times too small. The example
in the same texts (120 is 20 minutes) already used 10 seconds.
Correct the texts. The code does not change.
