* whisper : set bench data for each iteration
This commit updates whisper_bench_ggml_mul_mat_str to intialize the
tensors data for each iteration.
The motivation for this is that is currently possible for a previous
run's results, F32 values, to leak into the next run. When it is time
for the F16 iteration then F32 results can cause NaN values to appear
in the tensor values causing the F16 iteration to fail.

* ci : set GGML_NATIVE=OFF if x86_64
This commit sets GGML_NATIVE=OFF for x86_64 architectures.
The motivation for this is to try to get CI to pass and the theory is
that the libggml-cpu.so library in the ccache might have been built by a
runner that supports a different instruction set. When another runner
that does not support that instruction set tries to use it, it will fail
with a segmentation fault.
I'm not sure about this yet but going to try this out and if it does not
work I'll ssh into the runner to debug further.
