sysutils/ansible: Fix ansible.posix.mount - core 2.19 deprecation warning

Fix:

[WARNING]: Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
[DEPRECATION WARNING]: Passing warnings to exit_json or fail_json is deprecated. This feature will be removed from ansible-core version 2.23. Use AnsibleModule.warn instead.

ansible-collections/ansible.posix Issue #676 describes the issue above.
See https://github.com/ansible-collections/ansible.posix/issues/676.

Upstream commit ab8dfef from pull upstream request #670 addresses this bug.
See https://github.com/ansible-collections/ansible.posix/pull/670.

We cherry-pick the upstream pull request here to remove the annoying
message.
