LOG: [llvm][Support] Disable runOnNewStack test when threading is disabled

On our buildbot https://lab.llvm.org/buildbot/#/builders/122/builds/1478,
one of the new tests added by https://github.com/llvm/llvm-project/pull/136046
failed.

This is because on non-Apple Silicon platforms, the implementation
is to start a new thread, but when threading is disabled this is the
same as calling a function normally.

Added: 
    

Modified: 
    llvm/unittests/Support/ProgramStackTest.cpp

Removed:
