libstdc++: Sync __cpp_lib_ranges macro defined in ranges_cmp.h

r12-1606 bumped the value of __cpp_lib_ranges defined in <version>,
but this macro is also defined in <bits/range_cmp.h>, so it needs to
be updated there as well.

libstdc++-v3/ChangeLog:

	* include/bits/ranges_cmp.h (__cpp_lib_ranges): Adjust value.
