[PATCH] docs: conf.py: drop xindy rule

[Mauro Carvalho Chehab]

The rule as-is is wrong, as it was inverted. Besides that, after
retest building all repos with suggested LaTeX packages given
by sphinx-pre-install, I was unable to reproduce the issues
I saw with xindy in the past.

So, let's just drop. If anyone reports issues with xindy, we
may need to readd, but at the right way, e.g. {options}{pkgname}.
