buildman: Show the build rate at the end
It is interesting to note the number of builds completed per second to track machine performance and build speed. Add a 'rate' value at the end of the build to show this. Signed-off-by: Simon Glass <sjg@chromium.org>

+Build summary
+=============
+
+When buildman finishes it shows a summary, something like this:
+
+ Completed: 5 total built, duration 0:00:21, rate 0.24
+
+This shows that a total of 5 builds were done across all selected boards, it
+took 21 seconds and the builds happened at the rate of 0.24 per second. The
+latter number depends on the speed of your machine and the efficiency of the
+U-Boot build.
