Remove empty internal qiskit.providers.fake_provider.utils

[jakelishman]

This is an undocumented internal module, so not subject to the deprecation policy. The module has been empty since gh-13793 (and the handful of other qiskit.providers PRs that logically went with that one) in the Qiskit 2.0 transition, but since everything was using precise imports, we didn't notice the __init__ file was now useless.
