Fix for gles3 glTexImage2D format
Gles3 does not have support for GL_SRGB_ALPHA_EXT(0x8C42).
When the internal format is GL_SRGB8_ALPHA8(0x8C43) valid format
to use is GL_RGBA for gles3 as defined in
https://www.khronos.org/registry/OpenGL-Refpages/es3.0/html/glTexImage2D.xhtml
After this change,the test passes on gles3
Test: cts-tradefed run cts -m CtsVrTestCases --test
android.vr.cts.VrExtensionBehaviorTest#testSrgbBuffer
