selftests: kselftest_harness: fix Clang warning about zero-length format
Apparently it's more legal to pass the format as NULL, than
it is to use an empty string. Clang complains about empty
formats:
./../kselftest_harness.h:1207:30: warning: format string is empty
[-Wformat-zero-length]
1207 | diagnostic ? "%s" : "", diagnostic);
| ^~
