Checklist

• [x] I've prepended issue tag with type of change: [bug]
• [x] (If applicable) I've attached the script to reproduce the bug
• [x] (If applicable) I've documented below the DLC image/dockerfile this relates to
• [x] (If applicable) I've documented below the tests I've run on the DLC image
• [] I'm using an existing DLC image listed here: https://docs.aws.amazon.com/deep-learning-containers/latest/devguide/deep-learning-containers-images.html
• [x] I've built my own container based off DLC (and I've attached the code used to build my own image)

Concise Description: When I try to build DLC in my account '027412998179', I see random failures. Diving in & printing error messages points that somewhere in the code, we are treading account id as an integer and hence the code remove the prefix zeros.

pre-push container image in the log: 27412998179.dkr.ecr.us-east-1.amazonaws.com/sagemaker-inference-pyt-debug:1.7.1-cpu-py36-ubuntu18.04-2022-06-15-04-46-49-pre-push

DLC image/dockerfile: command: python src/main.py --buildspec pytorch/buildspec-1-7-1.yml --framework pytorch --image_types inference --device_types cpu --py_versions py3

Current behavior: Failed at safety check safety check command returned non-zero error code. This indicates that vulnerabilities might exist.

Expected behavior: Image build should work even for prefix 0 accounts
