build/deps: upgrade krb5 to 1.22.2

[tyson-redpanda]

Upgrades krb5 from 1.21.3 to 1.22.2. The memory leak fixes previously applied via patch are included in 1.22 upstream, so that patch is dropped. The NegoEx CVE patches (CVE-2026-40355, CVE-2026-40356) still apply cleanly to 1.22.2 and are retained.

@dotnwat fixed. The CI failures are resolved as well, just some flakes. Ready for another review please. No rush.
