The distro-specific setup always executes first and does make these call
redundant. Make sense.

Not related to this change, but at a glance it looks like this job
specific setup relies on using an Aptitude based distro. This does seem
slightly fragile if a job were to be configured with an unsupported
distro. Not anything we need to change here though.
