build: fix distcheck issues.

For some reason it seems that texi2dvi -o no longer forces --clean
mode, so we have stray TeX compilation files staying in top_builddir
since TeX is run from there.

While at it, upgrade the generation of the (completely obsolete)
reference card.  Target PDF.

* doc/local.mk (TEXI2DVI): Pass --build-dir.
(CLEANDIRS): More accurate.
(doc/refcard.dvi): Replace with...
(doc/refcard.pdf): this.
Adjust dependencies.
