Subject: [PATCH 1/9] kunit: test: Log the correct filter string in executor_test

KUnit's executor_test logs the filter string in KUNIT_ASSERT_EQ_MSG(),
but passed a random character from the filter, rather than the whole
string.

This was found by annotating KUNIT_ASSERT_EQ_MSG() to let gcc validate
the format string.

Fixes: 76066f93f1df ("kunit: add tests for filtering attributes")
