kunit: ubsan integration
Integrates UBSAN into the KUnit testing framework. It fails KUnit tests
whenever it reports undefined behavior.
When CONFIG_KUNIT=n, nothing is printed or even formatted, so this has
no behavioral impact outside of tests.
kunit_fail_current_test() effectively does a pr_err() as well, so
there's some slight duplication, but it also ensures an error is
recorded in the debugfs entry for the running KUnit test.
Print a shorter version of the message to make it less spammy.
