arp: fix the behavior on detecting an address duplication without IPv4 DAD
On receiving an ARP request that has the same source protocol address as
the own address, i.e., address duplication, the original behavior of
a kernel prior to supporing IPv4 DAD is to send an ARP reply. It is
the same with a latest kernel with DAD enabled. However, a latest
kernel without DAD sends back an GARP packet. Restore the original
behavior.
inet: send GARP on link up if DAD is disabled
This behavior was accidentally removed at rev 1.233.
tests, arp: add tests of address duplications without DAD
tests, arp: add tests for GARP on link up
