[PATCH v4] tools/testing:Fix the wrong format specifier

[Zhu Jun]

The format specifier in fprintf is "%u", that "%u" should use
unsigned int type instead.the problem is discovered by reading code.

 v1->v2:
 	modify commit info add how to find the problem in the log
 v2->v3:
 	Seems this can use macro WTERMSIG like those above usage, rather than
 	changing the print format.
 v3->v4:
 	Now the commit summary doesn't match the change you are making.
	 Also WTERMSIG() is incorrect for this conditional code path.
	 See comments below in the code path.

	 I would leave the v2 code intact. How are you testing this change?
	 Please include the details in the change log.
