Introduce the Error::UnexpectedError variant

The UnexpectedError variant is used when a libnitrokey function returns
a value that violates the function’s contract, for example if a function
returns a null pointer although it guarantees to never return null.
Previously, we returned a CommandError::Unspecified in these cases.
