LOG: [libc++][test] Fix size calculation for `unordered_map` in ABI test (#157006)

Currently,
`libcxx\test\libcxx\containers\associative\unord.map\abi.compile.pass.cpp`
consistently fails for 32-bit platforms.

There's an off-by-4 size calculation error for some `unordered_map`
specializations, possibly due to mistakenly ignoring some data member.

Added: 
    

Modified: 
    libcxx/test/libcxx/containers/associative/unord.map/abi.compile.pass.cpp

Removed:
