kunit: tool: fix extra trailing \n in raw + parsed test output
For simplcity, strip all trailing whitespace from parsed output. I imagine no one is printing out meaningful trailing whitespace via KUNIT_FAIL() or similar, and that if they are, they really shouldn't. `isolate_kunit_output()` yielded liens with trailing \n, which results in artifacty output like this: $ ./tools/testing/kunit/kunit.py run [16:16:46] [FAILED] example_simple_test [16:16:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29 [16:16:46] Expected 1 + 1 == 3, but [16:16:46] 1 + 1 == 2 [16:16:46] 3 == 3 [16:16:46] not ok 1 - example_simple_test [16:16:46] After this change: [16:16:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29 [16:16:46] Expected 1 + 1 == 3, but [16:16:46] 1 + 1 == 2 [16:16:46] 3 == 3 [16:16:46] not ok 1 - example_simple_test [16:16:46] We should *not* be expecting lines to end with \n in kunit_tool_test.py for this reason. Do the same for `raw_output()` as well which suffers from the same issue. This is a followup to [1], but rebased onto kunit-fixes to pick up the other raw_output() fix and fixes for kunit_tool_test.py.
