bug#26401: [PATCH] python-tryton (with no modules)

Sure!

tryton, and tryton related packages (especially the server side modules,
GNU Health, etc.) are numerous and complicated enough to deserve their
own separate file. You can put them in gnu/packages/tryton.scm.

For all practical purposes, I think it's best to assume that there is no
python3 genshi package. Instead, we should simply package
python2-genshi, and let the authors fix their python3 package. In any
case, tryton needs only python2-genshi. So, there is no urgent need for
the python3 genshi package. I guess, this also means that there will be
no python3 relatorio package.

Since you're not using any of `lambda*' features, you can just use `lambda' here.

Actually, this is not a big deal. We'll leave it as it is. If necessary,
I'll fix it before pushing.

Could you put these on the same line?

Use full names here, including the python version in the package name. I
mean the full name of "lxml" is "python2-lxml", not "python-lxml". Make
similar changes wherever applicable.

Also, in several places, there was a typo saying "pyton" instead of
"python". Please fix those.
