Fix tasks from failing in check_mode

By applying `check_mode: no` to the tasks collecting the current locale
and bash path, those tasks will be executed in the check mode and
subsequent tasks reyling on those won't fail.

See https://docs.ansible.com/ansible/latest/user_guide/playbooks_checkmode.html#enforcing-or-preventing-check-mode-on-tasks
for reference.
