[clang][test] Skip interpreter value test on Arm 32 bit

https://github.com/llvm/llvm-project/pull/89811 caused this test to fail,
somehow.

I think it may not be at fault, but actually be exposing some
existing undefined behaviour, see
https://github.com/llvm/llvm-project/issues/94741.

Skipping this for now to get the bots green again.
