Subject: [PATCH] fix PackedUser test

It is 120 bits long. @sizeOf returns 128, because, I guess, it tries to
word-align it (not byte-align it).

We are OK with non-word-aligned user struct, since it will have an
arbitrary []u8 slice right after it with the string data. However,
byte-alignment is important.
