Subject: [PATCH 06/17][RFC] ktest: Add NO_INSTALL option to not install for a test

From: Steven Rostedt <srostedt@...hat.com>

There's cases where running the same kernel over and over again
is useful, and being able to not install the same kernel can
save time between tests.

Add a NO_INSTALL option that tells ktest.pl to not install the
new kernel.
