<span class="idiff">## Summary
Using the gitlab-task-runner image, we are running a cronjob to backup our gitlab instance.  The exact command being run inside the `registry1.dso.mil/ironbank/gitlab/gitlab/gitlab-task-runner:13.8.0` to perform the backups is 
```
- /bin/bash
- -c
- cp /etc/gitlab/.s3cfg $HOME/.s3cfg &amp;&amp; backup-utility
```
This was working with the upstream registry.gitlab.com/gitlab-org/build/cng/gitlab-task-runner-ee:v13.8.1 image previously, but now using the image in registry one, we receive the following error at the end of the job:

```
2021-02-17 22:21:32 +0000 -- done
/usr/lib64/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in `require&#39;: cannot load such file -- object_storage_backup (LoadError)
        from /usr/lib64/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in `require&#39;
        from /usr/local/bin/object-storage-backup:3:in `&lt;main&gt;&#39;
```

## Steps to reproduce
In the `registry1.dso.mil/ironbank/gitlab/gitlab/gitlab-task-runner:13.8.0` container, run `bash backup-utility`

## What is the current bug behavior?
The backup job fails with the error.

```
2021-02-17 22:21:32 +0000 -- done
/usr/lib64/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in `require&#39;: cannot load such file -- object_storage_backup (LoadError)
        from /usr/lib64/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in `require&#39;
        from /usr/local/bin/object-storage-backup:3:in `&lt;main&gt;&#39;
```

## What is the expected correct behavior?
The job completes successfully and the backup tarball is uploaded to the configured s3 bucket.

## Possible fixes

The line of code where the import of the object-storage-backup rubygem is failing is in `usr/lib64/ruby/2.7.0/rubygems/core_ext/kernel_require.rb` at line 92:
```
</span><span class="idiff addition">    </span><span class="idiff"># If there are no unresolved deps, then we can use just try
    # normal require handle loading a gem from the rescue below.

    if Gem::Specification.unresolved_deps.empty?
      RUBYGEMS_ACTIVATION_MONITOR.exit
      return gem_original_require(path)</span><span class="idiff addition"> # line 92</span><span class="idiff">
    end
```
where `path` is ostensibly the path `/usr/local/bin/object-storage-backup`, which does exist in the container.

## Defintion of Done
- [ ] Bug has been identified and corrected within the container
