Changelog-None: `fuzz-hsm_encryption.c` hard codes the lengths sizeof(struct secret) as 32 and crypto_pwhash_argon2id_PASSWD_MAX as 4294967295. Replace the latter with the former to improve readability and maintainability. While at it, replace the `tal_free()` call on our secret key with `discard_key()`. This has the benefit of testing `discard_key()`.
Change in the fuzzing scheme of fuzz-hsm_encryption led to the discovery of test inputs that result in greater in code coverage. Add these inputs to the test's seed corpus.
