doc/start: refactor ABC test chart

Refactor the ABC test chart so that the information about which tests
have been run is presented in the center of the chart instead of, as it

-The charts below show how Ceph's requirements map onto various Linux
-platforms.  Generally speaking, there is very little dependence on
-specific distributions outside of the kernel and system initialization

+The chart below shows which Linux platforms Ceph provides packages for, and
+which platforms Ceph has been tested on.

+Ceph does not depend upon any specific distributions and can run on any
+distribution with supported kernels and system initialization packages (
+`sysvinit` or `systemd`).
