meta: Use GL_STREAM_READ for pbo created with GL_PIXEL_PACK_BUFFER
create_texture_for_pbo() is used by both _mesa_meta_pbo_GetTexSubImage()
and _mesa_meta_pbo_TexSubImage() functions with different PBO targets.
Use GL_STREAM_READ with GL_PIXEL_PACK_BUFFER and GL_STREAM_DRAW with
GL_PIXEL_UNPACK_BUFFER.
