[for-next][PATCH 7/9] ktest: Add PRE_KTEST_DIE for PRE_KTEST failures

[Steven Rostedt <rostedt@kernel.org>]

From: =?UTF-8?q?Ricardo=20B=2E=20Marli=C3=A8re?= <rbm@suse.com>

PRE_KTEST runs before the first test, but its return status is currently
ignored. A failing setup hook can leave the rest of the run executing in a
partially initialized environment.

Add PRE_KTEST_DIE so PRE_KTEST can fail the run in the same way
PRE_BUILD_DIE and PRE_TEST_DIE already can. Keep the default behavior
unchanged when the new option is not set.
