Disable MKL DNN build for ARM only due to JAX PR#23225

[gpupuck]

JAX PR#23225 jax-ml/jax#23225 introduced a JAX build error for ARM:

Internal triage indicates that the issue is deeper than it looks like. For now, we have to workaround the issue by disabling mkl dnn library for ARM, which won't effect us on the CUDA plugin builds.
