bind: upgrade 9.20.9 -> 9.20.11

Overview of changes in bind 9.20.11
==================================
Security Fixes:
1. Fix a possible assertion failure when stale-answer-client-timeout is set to 0.
2. In specific circumstances the named resolver process could exit with an
   assertion failure when stale answers were enabled and the stale-answer-client-timeout
   configuration option was set to 0. This has been fixed. (CVE-2025-40777) [GL #5372]
