src/t_attr_corruption: covert value to little endian order

generic/529 always fails on ppc64 or s390x big-endian machine as:

  set posix acl: Operation not supported

Due to the members of struct posix_acl_xattr_entry/header need to be
little-endian byte order, so use htole*() helper to make sure that.
