Do not generate a `truncated:` for _parsing_ u8[] at end of struct 

Our previous rule had been that all u8 arrays needed a `truncated:`
section.  That's fine if the arrays have a length, but not if their
length extends to the end of the structure: such arrays can't be
truncated.

This time I also add a test to make sure change works.
