linuxdoc-tools-native: disable doc builds requriing latex and dvips

This fixes the following errors during do_install on hosts which have
latex and/or dvips installed:

fmt_latex2e::postASP: LaTeX first run problem. Aborting ...

dvips: ! DVI file can't be opened.

Our goal is to have native versions of these tools eventually. Until
then, disable these parts of the documentation install process.

This fixes [BUGID #774].

+Disable building documentation which requires the latex utility.
+This patch should be dropped once we include a native version of
+latex.
