libstdc++: Correctly call _string_types function

flake8 points out that the new call to _string_types from
StdExpAnyPrinter.__init__ is not correct -- it needs to be qualified.

libstdc++-v3/ChangeLog:

	* python/libstdcxx/v6/printers.py
	(StdExpAnyPrinter.__init__): Qualify call to
	_string_types.

(cherry picked from commit 4bf77db70e2521dc89f9d7f51c7ae6e58a94b4f9)
