Fix a spurious test where a condition is always true:

      if ((cfg->skipto != NULL) && (ctx->flags | ENC_SKIPTO)) {
                                    ^^^^^^^^^^^^^^^^^^^^^^^

This is apparently harmless because, in 'xml2enc_filter_init', the ENC_SKIPTO bit of 'flags' is set to ENC_SKIPTO if 'skipto' is non-NULL.
