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
