[clang] Mark tests as unsupported when targeting z/OS (PR #107916)

[Sean Perry via cfe-commits]

https://github.com/perry-ca created https://github.com/llvm/llvm-project/pull/107916

Set up these tests so these are marked as unsupported when targeting z/OS.  Most would already be unsupported if you ran lit on z/OS.  However, they also need to be unsupported if the default triple is z/OS.
