pkg/pillar: make ioBundleError deepcopy-able

[christoph-zededa]

error types very often have private members that cannot be marshalled with json.Marshal

we fix this by only storing the error type and the error string (err.Error()) as values in uppercase members of our own ioBundleError type

log output:

json Unmarshal in deepCopy: json: cannot unmarshal object into Go struct field IoBundleError.IoBundleList.Error.Errors of type error
