Just like I suspected, there was a bug in EXEC_BACKEND, although a bit
different from what I guessed - the worker state in shmem was zeroed
every time, not just once. And a second issue was child_process_kinds
got out of sync with BackendType (mea culpa).

For me, this passes all CI tests, hopefully cfbot will be happy too.
