gl: do not allocate the target texture of an EGLImage

Browse source 
The target texture of an EGLImage is the texture bind just
before calling glEGLImageTargetTexture2D.

As we currently only support a gl texture as the source of an EGLImage
the gl texture is actually already allocated when creating the eglimage.

I also see some cases where it fails to upload an eglimage when
glTexImage2D is called on the target.
