Re: xentools411 fails build

[Martin Husemann <martin%duskware.de@localhost>]

This kind of warning (used with -Werror) breaks all sysutils/xentools*
builds with gcc >= 7.

I started fixing some for xentools48, but ran out of time and gave up
on xen instead.

Elide string truncation warning with newer gcc.
