[RFT PATCH -perfbook v3 v3 2/4] Makefile: Fix issues WRT parallel runs of pdflatex

[Akira Yokosawa <akiyks@gmail.com>]

There is a couple of minor issues in Makefile WRT parallel runs of
runfirstlatex.sh.

When some of perfbook-xxx.tex files already exist, runfirstlatex.sh
for other main perfbook-yyy.tex can be invoked prematurely before
that .tex file gets ready.
Fix it by adding stricter dependencies of perfbook-xxx.aux on
perfbook-xxx.tex.

Also sort out dependencies around here.
autodate.tex now depends only on files in the Git repo.
Instead, perfbook_flat.tex acts as a barrier between the file
conversion phase and the pdflatex phase.
