Replace krb5 1.21.3 with 1.22.2. The memory leak fixes previously applied via patch are included in 1.22 upstream. The NegoEx CVE fixes (CVE-2026-40355, CVE-2026-40356) patch still applies cleanly and is retained until they land upstream.

krb5 1.22.2 has a bug where struct kdclist and kdclist_entry are defined inside a KRB5_DNS_LOOKUP conditional, but the functions using them are outside it. When configure doesn't define KRB5_DNS_LOOKUP (as in the Bazel sandbox), the structs are incomplete at compile time. Cherry-pick the upstream fix from master (3c672ca).
