doc: prefer the ".gv" extension to ".dot"

See http://marc.info/?l=graphviz-devel&m=129418103126092 for the
motivation (basically, some word processor now uses *.dot).

* doc/figs/example-reduce.dot: Rename as...
* doc/figs/example-reduce.gv: this.
* doc/figs/example-shift.dot: Rename as...
* doc/figs/example-shift.gv: this.
* doc/figs/example.dot: Rename as...
* doc/figs/example.gv: this.
* doc/local.mk: Adjust.
