i965/tex_subimage: use meta only for OpenGL ES 3.0 chipsets

GL_PIXEL_UNPACK_BUFFER and GL_PIXEL_PACK_BUFFER are used in meta PBO,
but those capabilities are available only in OpenGL ES 3.0 parts,
so we skip _mesa_meta_pbo_TexSubImage() for gen4 and earlier.

This workaround avoids the hazi font bug #92323# affecting X3100 and X4500,
with neglibile impact in performance for gen5 and later.

This patch is complementary to the former in i965/tex_image.
