--update: when used, do not generate the output files

Browse Source 
It is inconvenient that we also generate the output files when we
update the grammar file, and it's somewhat unexpected.  Let's not do
that.

* src/main.c (main): Skip generation when --update is passed.
* src/getargs.c (usage): Update the help message.
* doc/bison.texi (Bison Options): Likewise.
* tests/input.at: Check that we don't generate the output.
