SCRD-5506 Fixed issue when CONF.paths.playbooks_dir doesn't exist

Before ready-deployment playbook ever gets run,
CONF.paths.playbooks_dir doesn't exist. When run
config-processor-run playbook, it failed to generate a
temp file with a encryption key in that dir. The fix is not
to generate the temp file when CONF.paths.playbooks_dir
is not there.
