[PATCH net-next v3 08/11] selftests: kselftest_harness: separate diagnostic message with # in ksft_test_result_code()

[Jakub Kicinski <kuba@kernel.org>]

According to the spec we should always print a # if we add
a diagnostic message. Having the caller pass in the new line
as part of diagnostic message makes handling this a bit
counter-intuitive, so append the new line in the helper.
