Add ingnore_errors: true for Search and Configure priv commands on base/audit role

[Persimmonboy]

Added the ignore_errors: true parameter to Ansible tasks to prevent interruptions caused by errors when searching for and logging privileged commands on base/audit role for infra-prod-base-ext zuul job.

These changes allow the playbook to continue execution even if some commands return errors related to non-existent container binaries. Examples of such errors include:

fatal: [executor4.apimon.eco.tsi-dev.otc-service.com]: FAILED! => {
"changed": false,
"cmd": "df --local -P | awk {'if (NR!=1) print $6'}  \\\n| xargs -I '{}' find '{}' -xdev -type f \\( -perm -4000 -o -perm -2000 \\) -print 2>/dev/null\n",

}

"rc": -13
}

These errors occurred sporadically on various hosts, often due to attempts to access binaries from non-existent containers. Adding ignore_errors: true helps ensure the playbook runs more reliably by ignoring such transient errors.
