[for-next][PATCH 09/23] ktest.pl: Allow for the config-bisect.pl output to display to console

[Steven Rostedt]

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

When commands are run in ktest, they are only displayed in the ktest log
file, but that is not sufficient for outputting the display for config
bisects. The result of a config bisect is not shown.

Add a way to display the output of "run_command" which is the subroutine
used by ktest to execute commands. Use this feature to display the output of
config-bisect.pl executions to see the progress as well as the result.
