tests/tcg/multiarch/linux-test: use portable alternative for dirent64

Browse Source 
dirent64 and readdir64 are glibc-specific and not portable to other
C libraries such as musl. Define _FILE_OFFSET_BITS=64 instead, which
portably instructs all libc implementations to use 64-bit file offsets,
making readdir() and struct dirent equivalent to their 64-bit variants.
