Remove custom source implementation for Error
This patch removes the custom implementation of the source method of the std::error::Error trait for the error::Error type. This means that the default implementation is used that always returns None. The reason for this change is that we already print the error message of the source error in the Display implementation. This leads to a duplicated error message if both Display and source are checked, for example with anyhow’s error formatting. See this thread for more information: https://lists.sr.ht/~ireas/nitrokey-rs-dev/%3C6e0b4dc8-9059-a113-e98e-b49e52818c75%40posteo.net%3E
