The ABI for disabling streaming mode via ptrace is to do a write via the SVE register set. Following the recent round of fixes to the ptrace code we don't support this operation on systems without SVE, which is detected as failures by fp-ptrace. Update the program so that it knows that this operation is not currently supported.
