Suppress texture-upload-size.html on Android for OpenGL ES

The test conformance/textures/misc/texture-upload-size.html is flaky on
Android with the OpenGL ES backend:

https://ci.chromium.org/p/chromium/builders/try/android_angle_rel_ng/10962
https://ci.chromium.org/p/chromium/builders/try/android_angle_rel_ng/10935
https://ci.chromium.org/p/chromium/builders/try/android_angle_rel_ng/10931
https://ci.chromium.org/p/chromium/builders/try/android_angle_rel_ng/10871

This CL will suppress the test while the issue is investigated.
