The progs/es2/xegl/tri.c demo fails using, eglQuerySurface() with
EGL_SURFACE_TYPE.
Only eglGetConfigAttrib can query EGL_SURFACE_TYPE.
This patch replaces that with querying EGL_CONFIG_ID, then using that
ID to call eglChooseConfig and using that config to call
eglGetConfigAttrib() with EGL_SURFACE_TYPE.
