ansible: Fix several file permission mask format

From ansible documentation [1]:
"""
For those used to /usr/bin/chmod remember that modes are actually octal
numbers. You must either add a leading zero so that Ansible's YAML
parser knows it is an octal number (like 0644 or 01777) or quote it
(like '644' or '1777') so Ansible receives a string and can do its own
conversion from string into number.
Giving Ansible a number without following one of these rules will end up
with a decimal number which will have unexpected results.
