[PATCH v3] selftests:Fix printf format string in kselftest_harness.h

[Zhu Jun <zhujun2@xxxxxxxxxxxxxxxxxxxx>]

'%u' in format string requires 'unsigned int' in __wait_for_test()
but the argument type is 'signed int' that this problem was discovered
by reading code.use macro WTERMSIG like those above usage to
fix the wrong format specifier.
