hash: bugfix: don't trim seed to 32 bits.

This relates to the November 2021 commit
9108e9f8f4434fb29200b08a4b576df47c407c01:

  hash: 64 bit string and buffer hashing and seeds.

In the hash constructor, a 32 bit cast was left
behind, needlessly reducing the seed value to 32
bits on 64 bit platforms.

* hash.c (do_make_hash): Don't convert the ucnum
value to u32_t; just store it.
