Jail admin sudo validation should use the jail visudo

[clementmartin]

the following task uses the host sudo to validate the jail sudoers file:

- name: add jail admin to sudoers
  lineinfile:
    dest:  "{{ jails_dir }}/{{ jail_master_tpl_name }}/usr/local/etc/sudoers"
    line: "{{ jails_admin_user }} ALL=(ALL) NOPASSWD: ALL"
    validate: 'jexec {{ jail_master_tpl_name }} visudo -cf %s'

It should use the jail sudo.

Simply wrapping the validation command does'nt work because ansible pass the full path from the host root filesystem, which obviously does'nt exist on the jail.
