Fix Debian build rules to reflect changes in texi2html (Debian Bug #317862)

Texi2html's behavior changed recently: if it is invoked with
-split=chapter, old versions place the HTML files in the same
directory as the documentation source, whereas new versions place the
generated files in a subdirectory.
