esp8266/modpybuart: Fix UART parity setting.
The configuration bits for the UART register were wrong and the parity
couldn't be enabled, because the exist_parity member hasn't been updated. I
took this ESP8266 register description (http://esp8266.ru/esp8266-uart-reg/)
as reference.
Verification has been done with a logic analyzer.
