    GH-48176: [C++][Parquet] Fix arrow-ipc-message-internal-test failure (#48166)
    
    **Rationale for this change**
    
    Fix `arrow-ipc-message-internal-test` on big endian systems by passing endianness explicitly.
    
    **Are these changes tested?**
    
    Yes. The changes are tested on s390x arch to make sure things are working fine. The fix is also tested on x86 arch, to make sure there is no new regression introduced.
    
    **Are there any user-facing changes?**
    
    No
