Subject: [PATCH] Use the role from the crond context for system job contexts.
New SELinux policy added multiple roles for the system_u user on crond_t.
The default context returned from get_default_context_with_level() is now
unconfined_t instead of system_cronjob_t which is incorrect for system cron
jobs.
We use the role to limit the default context to system_cronjob_t.
