net/arp-scan: Disable promiscuous mode

promiscuous mode are very annoying.

This backports an upstream patch to disable the unnecessary promiscuous
mode in arp-scan.

++      * arp-scan.h: Disable promiscuous mode on the network interface.
++        Promiscuous mode is not required to receive ARP response packets
++        because they are unicast packets directed to the scanning host.
++
+ 2022-12-10 Roy Hills <[email protected]>
+ 
+       * configure.ac: Set version to 1.10.0.
