Create slowroll.yaml (#1674)

Slowroll.yaml is almost indentical to leap_160.yaml and tumbleweed.yaml
but will eventually give users the option to install slowroll through
agama. was unable to provide translations since i only speak english and
i am unsure if there other arch's for slowroll besides x86_64

Slowroll is currently the only option not available to install via agama
that (i believe) is not planning on using something different (like
Aeon, Kalpa and Leap Micro)
