Zcu: fix ZOIR cache bugs
* When saving bigint limbs, we gave the iovec the wrong length, meaning
bigint data (and the following string and compile error data) was corrupted.
* When updating a stale ZOIR cache, we failed to truncate the file, so
just wrote more bytes onto the end of the stale cache.
