This adds a new SELinux module "bacula" for the bacula backup application. Directly mapping bacula on the existing backup
module was not feasible (partially because it uses both a general domain and an administrative client domain).

Policy provided by Stan Sander through https://bugs.gentoo.org/show_bug.cgi?id=396241
