base58: Use alternate form to print hex

Currently we are manually adding `0x` in calls to `write!`, this is
unnecessary since the alternate form already adds the `0x`.

Was verified with
```
    #[test]
    fn bad_checksum_error_hex_format() {
        let want = "invalid base58 character 0xab";
        let got = format!("{}", Error::BadByte(0xAB));
        assert_eq!(got, want)
    }
```

Use alternate form to print hex.
