client: unnecessary Apple silicon fingerprinting

Issue

The external module used for fingerprinting Apple Silicon, go-m1cpu runs the majority of it's code in an init function. This means that it runs on every Nomad CLI command for Apple Silicon users, and has led to some odd bugs, like #27799.

Ideally, we should make an upstream contribution to this repository and change it to use something else for initialization besides an init func.
