libstdc++: Fix outdated comment about standard integer types

The long long and unsigned long long types have been standard since
C++11, so are not extensions. There are also the char8_t, char16_t and
char32_t types. Just refer to the standard integer types, without saying
how many there are.

libstdc++-v3/ChangeLog:

	* include/bits/cpp_type_traits.h: Fix outdated comment about the
	number of standard integer types.
