That would only solve the problem for gsfonts-x11, but not for
anything else using dh_installxfonts. I think, to be safe the hack
would need to be applied to xfonts-utils's dependencies, which is all
kinds of ugly, but at least should always work, at the cost of
complicating the upgrade path.

I guess the correct solution though, is to change update-fonts-* and
any other script in xfonts-utils calling mkfont* from other maintainer
scripts, to only run if xfonts-utils itself is configured or being
configured, and calling these through xfonts-utils maintainer scripts
too, so that if xfonts-utils and something else using it like gsfonts-x11
are both unpacked on the same run, the actual update-fonts-* executions
will be delayed until xfonts-utils is itself configured, at which point
the scripts should be able to run. I don't think this would be much
more difficult to prepare.
