blender_io_ttyd: Fix display list alignment

Display lists must be aligned by 32 bytes. On Dolphin this doesn't seem
to matter, but on real hardware this is required. We previously ensured
internal alignment of the mesh section but didn't ensure that the
section itself is placed with 32-byte alignment.
