Fix permissions of tmp files

When running kolla-ansible as non-root users the tmp files will
be created with become user as owner and mode 0600. This way the user
running kolla-ansible is not able to read the generated files. This
is necessary because of the use of the lookup method, which will
not run as become user.

TrivialFix
