BottleRocket configures setttings.network.hostname incorrectly when using resource based names

[tzneal]

Platform I'm building on:

A VPC with subnets configured for resource based names.

What I expected to happen:

[root@admin]# apiclient  get settings.network.hostname
{
  "settings": {
    "network": {
      "hostname": "i-1234567890abcdef0.compute.internal"
    }
  }
}

What actually happened:

[root@admin]# apiclient  get settings.network.hostname
{
  "settings": {
    "network": {
      "hostname": "ip-192-168-131-0.us-west-2.compute.internal"
    }
  }
}

How to reproduce the problem:

1. Configure a subnet with resource based naming
2. Launch a BottleRocket instance into this subnet
