Adjust index number of tuple pretty printer

The tuple pretty printer uses 1-based indeces which is quite confusing
considering the access to the same values with the std::get functions
uses 0-based indeces.  This patch changes the pretty printer since
this is not a guaranteed API.

libstdc++-v3/ChangeLog:

	* python/libstdcxx/v6/printers.py (class StdTuplePrinter): Use
	zero-based indeces just like std:get takes.
