testsuite: Fix up consteval-prop21.C for 32-bit targets [PR115986]

The test fails on 32-bit targets (which don't support __int128 type).
Using unsigned long long instead still ICEs before the fix and passes
after it on those targets.

	PR c++/115986
	* g++.dg/cpp2a/consteval-prop21.C (operator "" _c): Use
	unsigned long long rather than __uint128_t for return type if int128
	is unsupported.
