[U-Boot] [PATCH v6 1/6] env: add the same prefix to error messages to make it detectable by tests

[Quentin Schulz]

The error message should start with `## Error: ` so that it's easily
detectable by tests without needing to have a complex regexp for
matching all possible error message patterns.

Let's add the `## Error: ` prefix to the error messages since it's the
one already in use.
