Fix privilege escalation ('become') on localhost.

[eliba]

For some context: In my local setup, passwords ansible_password and ansible_become_password get automatically set through group_vars/all.yml:

ansible_password: "{{ lookup('passwordstore', 'IT/system_logins/' + inventory_hostname + '/' + ansible_user) }}"
ansible_become_password: "{{ lookup('passwordstore', 'IT/system_logins/' + inventory_hostname + '/' + ansible_user) }}"

Those vars are preserved when doing delegate_to: localhost and tasks fail when the requested password does not exist. (AFAIK localhost is not part of group all, but since it gets delegated from one of the hosts in ansible_play_batch, those vars are preserved)

If such a password entry exists, the task runs through flawlessly (although the password does not get used), but if the password entry does not exist, the lookup plugin will fail.

Thanks for the work that went into this role already, it is a great one that gets the job done!
