testsuite; Fix unprotected-allocas-1.c at -O3 [PR121684]

The problem here is after  r16-101, the 2 functions containing alloca/VLA
start to be cloned and then we un-VLA happens in using_vararray so this
is no longer testing what it should be testing.
The obvious fix is to mark using_vararray and using_alloca as noclone too.

Pushed as obvious after a quick test to make sure it is now working.

gcc/testsuite/ChangeLog:

	PR testsuite/121684
	* c-c++-common/hwasan/unprotected-allocas-0.c: Mark
	using_vararray and using_alloca as noclone too.
