Rename Version::Errors to Image::Errors

The Version interface is a public interface, and errors are being
added to it:
https://gerrit.openbmc-project.xyz/#/c/openbmc/phosphor-dbus-interfaces/+/13836/

This conflicts with the internal Version errors, so rename the
internal one to an Image namespace since that's not a public
interface and make more sense since the errors deal with failures
during image file extraction.

Tested:
  Uploaded an invalid tar file (u-boot.bin) and the new Image::Error
  was created:

    "/xyz/openbmc_project/logging/entry/2": {
      "AdditionalData": [
        "PATH=/tmp/images/u-boot.bin",
        "_PID=1348"
      ],
      "Description": "An internal BMC error occurred",
      "EventID": "None",
      "Id": 2,
      "Message": "xyz.openbmc_project.Software.Image.Error.UnTarFailure",
