mtr: Fix crash in report mode due to string_fortified.

I was made aware of this issue by a Discord user who tried to find out why
duckduckgo was misbehaving with their routing. They were using the `-w` flag.
I tried to generate a similar report and ended up running into the same issue.
I was running Arch Linux however! Turns out traviscross/mtr#508 is related and
the there mentioned fix also works here.

Refs traviscross/mtr#508.
