[sanitizer] Fix build with _FILE_OFFSET_BITS=64. 

Sanitizer source is not affected by _FILE_OFFSET_BITS in general,
but this one file must be built with 32-bit off_t. More details in the code.

// Tests in this file assume that off_t-dependent data structures match the
// libc ABI. For example, struct dirent here is what readdir() function (as
// exported from libc) returns, and not the user-facing "dirent", which
// depends on _FILE_OFFSET_BITS setting.
// To get this "true" dirent definition, we undefine _FILE_OFFSET_BITS below.
