vc4: Fix write-only texsubimage when we had to align.
We need to make sure that when we store the aligned box, we've got
initialized contents in the border. We could potentially just load the
border area, but for now let's get text rendering working in X (and fix
the GL_TEXTURE_2D errors in piglit's texsubimage test and
gl-2.1-pbo/test_tex_image)
