Bug#299843: tetex-base: another circular link

[Julian Gilbey <jdg@debian.org>]

Package: tetex-base
Version: 3.0-2

[Realised it makes more sense to put this in the BTS so it doesn't get
lost]

I got another circular symlink issue upgrading from 2.0.2-something to
3.0-2: /etc/texmf/context/cont-usr.tex

I presume it's because
/usr/share/texmf/tex/context/config/cont-usr.tex is a symlink to
/etc/texmf/context/cont-usr.tex but
/usr/share/texmf/tex/context/config used to be a symlink to
/etc/texmf/context
and therefore is the same as bug #297614.
