Use "babel only" for some Spanish manuals

Many of our Spanish documents use babel-specific features in the
documents, e.g. to write "sin" in Spanish ("sen"). Because babel
seems to have good support for Spanish, I am setting the "Always
babel" for the manuals.

This fixes several LuaTeX tests with non-TeX fonts. A XeTeX test is
also reverted accordingly.
