[for-next][PATCH 1/9] ktest: Add timings for commands

[Steven Rostedt]

From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>

I find that I usually like to see how long a make or other command takes,
and adding a start and end time and reporting how long each command runs
(in seconds) is helpful.
