For reasons we haven't been able to work out, the aarch64 EC2 image now regularly exceeds the output image size on hydra.nixos.org. As a workaround, set this back to being statically sized again. The other images do seem to build - it's just a case of the EC2 image now being too large (occasionally non-determinstically).
