Ignore big-endian targets in UI tests with raw bytes

Some `const` UI tests have raw bytes in their output that are sensitive to the target endianness. We could consider something like the directive `stderr-per-bitwidth` for endian, but we only ever test little-endian in CI, so that would likely bit rot. For now, just ignore big-endian.
