Return non-zero in mcurses_phyio_init to work properly.

Hi ChrisMicro,

Many thanks for your work porting mcurses to the Arduino, lots of us grey-beards appreciate it (it's thirty-odd years since I last wrote a (working, useful) curses program). :-)

Using mcurses with an ESP8266 (building with PlatformIO under Linux), I'm seeing the same thing as Jasoroony, though; the graphics character set isn't available unless I change mcurses_phyio_init() to return a non-zero value.

Other than that, it works remarkably well and remarkably quickly on an ESP01S (using a telnet connection).

Best wishes from Japan,

      -John-
