[RFC 6/7] selftests: kselftest_harness: let ksft_test_result_code() handle line termination

[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.
