Fix FreeBSD tests and CI Daily issues. (#8438)

* Add bash temporarily to allow sentinel fd leaks test to run.
* Use vmactions-freebsd rdist sync to work around bind permission denied
  and slow execution issues.
* Upgrade to tcl8.6 to be aligned with latest Ubuntu envs.
* Concat all command executions to avoid ignoring failures.
* Skip intensive fuzzer on FreeBSD. For some yet unknown reason, generate_fuzzy_traffic_on_key causes TCL to significantly bloat on FreeBSD resulting with out of memory.
