Fix CVE(s): CVE-2026-43964

  • SECURITY UPDATE: buffer over-read when an enhanced status code is not followed by any text
    • debian/patches/CVE-2026-43964.patch: stop dsn_split() advancing the cursor past the terminating NUL when the status code occupies the whole string (upstream 4992c82ad9, postfix-3.8.16).
    • CVE-2026-43964
  • Recognise Linux 5 and 6 build hosts
    • debian/patches/support-linux-5-and-6-build-hosts.patch: postfix 3.3.0 predates Linux 5, so makedefs aborted with "Unknown system type" on the EL9 (5.14) build nodes before compiling anything. Widen the case list and add LINUX5/LINUX6 to the existing LINUX2/3/4 sys_defs.h group, so the defines match a Linux 4 host exactly.
