[PR] Adjust Variant size expectation for s390x architecture [arrow-rs]

["frantisekz (via GitHub)" <gi...@apache.org>]

   # Which issue does this PR close?
   - Closes #10026 .
   
   # Rationale for this change
   
   The Variant enum has a different size on s390x (72 bytes) compared to other 64-bit architectures (80 bytes) due to architecture-specific alignment and padding requirements.
   
   # What changes are included in this PR?
   
   This change adds a conditional compilation check to expect 72 bytes on s390x while maintaining the existing 80-byte expectation for other 64-bit platforms. This ensures the size check passes on s390x without compromising the performance validation on other architectures.
   
   # Are these changes tested?
   
   Build-time test only
   
   # Are there any user-facing changes?
   
   N/A
