[committed] libstdc++: Fix condition for __cpp_lib_shared_ptr_arrays

[Jonathan Wakely]

Tested powerpc64le-linux, pushed to trunk.


I changed the preprocessor condition from <= to < in r12-6574 which
meant the macro was not defined by <version> for C++17.

libstdc++-v3/ChangeLog:

	* include/std/version (__cpp_lib_shared_ptr_arrays): Fix
	condition for C++17 definition.
