[tlbuild] Broken dvi2tty tests

[Mojca Miklavec]

Hi,

after https://tug.org/svn/texlive?view=revision&revision=63193
(dvi2tty: ver6.0.2) the tests started failing on some platforms,
notable the 32-bit ones:
- armhf-linux (Debian 10)
- 1386-linux (Debian 9)
- i386-freebsd (FreeBSD 12.3)
- i386-openbsd (OpenBSD 6.9 and 7.0)
- i386-solaris (Solaris 10)

As far as I can see all the 64-bit platforms work just fine.
It looks like an overflow of a 32-bit (un?)signed integer.
