skia: wrong calling convention on eglGetPlatformDisplayEXT

When attempting to run the release compile of nanobench on windows, I would
immediately crash due to c++'s buffer security check.

This was caused by calling the function with the wrong calling
convention.  I'm not sure how this ever worked for anyone.

Anyway, fix is to use eglext.h's version of the function definition.
