graph: output foo.gv by default, instead of *.dot

Browse Source 
That change was started in Bison 3.4.  The announcement for 3.7 stated
that in Bison 3.8 we would use *.gv by default.

* src/files.c (compute_output_file_names): spec_graph_file defaults
too *.gv.
* doc/bison.texi, examples/c++/calc++/local.mk, tests/output.at:
Adjust.
