since time64 switchover has changed the size and layout of the struct anyway, take the opportunity to fix it up so that it can be shared between 32- and 64-bit ABIs on the same system as long as byte order matches. the ut_type member is explicitly padded to make up for m68k having only 2-byte alignment; explicit padding has no effect on other archs. ut_session is changed from long to int, with endian-matched padding. this affects 64-bit archs as well, but brings the type into alignment with glibc's x86_64 struct, so it should not break software, and does not break on-disk format. the semantic type is int (pid-like) anyway. the padding produces correct alignment for the ut_tv member on 32-bit archs that don't naturally align it, so that ABI matches 64-bit. this type is presently not used anywhere in the ABI between libc and libc consumers; it's only used between pairs of consumers if a third-party utmp library using the system utmpx.h is in use.
