RFS: arp-scan (fix #910140 and more changes)

Hello,
I'm working on the arp-scan package and it would be interesting to upload a new revision.

https://salsa.debian.org/pkg-security-team/arp-scan/tree/arp-scan_1.9.5-2

I created a new branch (arp-scan_1.9.5-2) and after review and upload I will do a merge request.

The cowbuilder is working perfectly but CI Test on Salsa didn't work.

Thanks for review and upload or point out improvements.

Regards,

Thiago
