i965: Reject unsupported formats in glEGLImageTargetTexture2D()

If the EGLImage's format is not a supported texture format according to
brw_surface_formats.c, then refuse to create the miptree. This follows
the precedent in glEGLImageRenderbufferStorage (implemented by
intel_image_target_renderbuffer_storage), which rejects the EGLImage's
format if is not renderable.
