c++: Fix clang problem [PR 98340]

Clang didn't like sizeot (uintset::value) in a templated context.  Not sure
where the problem lies -- ambiguous std, gcc erroneous accept or clang erroneous
reject.  Anyway, this avoids that construct.

	PR c++/98340
	gcc/cp/
	* module.cc (uintset<T>::hash::add): Use uintset (0u).MEMBER,
	rather than uintset::MEMBER.
