tar driver does not work on MacOS

I am trying to run some basic fileContentTests and fileExistenceTests on MacOS with tar driver

```
schemaVersion: 2.0.0

fileContentTests:
- name: "os-version"
path: "/etc/os-release"
expectedContents: [
'NAME="CentOS Linux"',
'ID="centos"',
'ID_LIKE="rhel fedora"',
'VERSION_ID="7"',
'CPE_NAME="cpe:/o:centos:centos:7"',
'HOME_URL="https://www.centos.org/"',
'BUG_REPORT_URL="https://bugs.centos.org/"',
'CENTOS_MANTISBT_PROJECT="CentOS-7"',
'CENTOS_MANTISBT_PROJECT_VERSION="7"',
'REDHAT_SUPPORT_PRODUCT="centos"',
'REDHAT_SUPPORT_PRODUCT_VERSION="7"',
]
```

With this bazel test setup
```
container_test(
name = "base-container-test-tar",
size = "small",
configs = ["testdata/base-container-test.yml"],
driver = "tar",
image = "@centos-7//image:image",
)
```

Which resulted in the following error
```

I am using bazel rules_docker on latest HEAD https://github.com/bazelbuild/rules_docker/commit/e15c9ebf203b7fa708e69ff5f1cdcf427d7edf6f

This test passed just fine when run on Linux + tar-driver or MacOS + docker-driver. But not MacOS + tar-driver.
