Remove error stutter

When podman gets an error it prints out "Error: " before
printing the error string.  If the error message starts with
error, we end up with

Error: error ...

This PR Removes all of these stutters.

logrus.Error() also prints out that this is an error, so no need for the
error stutter.

[NO NEW TESTS NEEDED]
