libstdc++: Fix atomic and error_code printers for versioned namespace

This fixes the printers to work with std::__8::atomic and
std::__v8::ios_errc and std::__v8::future_errc.

libstdc++-v3/ChangeLog:

	* python/libstdcxx/v6/printers.py (StdErrorCodePrinter): Make
	lookup for ios_errc and future_errc check versioned namespace.
	(StdAtomicPrinter): Strip versioned namespace from typename.
