Fix: Bug #13214 AttributeError: 'NoneType' object has no attribute 'text'

[indgy]

This fix resolves bug #13214

I was seeing this error on my pfsense install with ArpWatch enabled

This code checks the element exists before trying to assign the text value, if it does not exist an empty string is assigned instead.

As a part of this pull request, you must increase PORTVERSION or add a PORTREVISION line in the package Makefile. Without this version increase, the package will not be rebuilt to include the new change.

Apologies I am not familiar with the FreeBSD port make process, I've bumped the port revision number.

There is an issue reported by portlint but it existed before my edits
FATAL: Makefile: [1]: $FreeBSD$ is deprecated in Git.

Shall I remove that line in this PR too?

That can be left alone, no need to worry about it.
