We should probably add those flushes to the kselftest helpers (eg, the
one at the end of the program should be in ksft_finished()) if they're
needed.  It ought to be redundant though, we do set stdout to be line
buffered in ksft_print_header() which means that either ksft_finished()
will print a line and flush or for abort_hooks() it's immediately before
we call exit() which should do the right thing anyway.  If exit() isn't
flushing I'd not be optimistic that fflush() is going to work.
