hardened buildah container runs as non-existent user
Summary
It appears the build user is added as UID 1000, but the container is entered as UID 1001, which does not exist. This causes some commands to fail.
Steps to reproduce
docker run -it --entrypoint "/bin/bash" ${imageID} whoami grep ^10 /etc/passwd
What is the current bug behavior?
Many commands run in the container throw "cannot find name for user ID 1001" error
What is the expected correct behavior?
Login as an existing user, whoami finds the user
Relevant logs and/or screenshots
whoami: cannot find name for user ID 1001
bash-4.4$ grep 100 /etc/passwd
games:x:12:100:games:/usr/games:/sbin/nologin
build:x:1000:1000::/home/build:/bin/bash```
```USER 1001```
## Possible fixes
https://repo1.dso.mil/dsop/opensource/containers/buildah/-/blob/development/Dockerfile#:~:text=USER%201001,53
alternately, add ```-u 1001``` when creating the user at https://repo1.dso.mil/dsop/opensource/containers/buildah/-/blob/development/Dockerfile#:~:text=RUN-,useradd%20build,-%26%26%20%5C
## Tasks
- [ ] Bug has been identified and corrected within the container
