Subject: tools/testing/selftests/kcmp/kcmp_test.c: print reason for failure in kcmp_test
I was curious why sys_kcmp wasn't working, which led me to the testcase.
It turned out I hadn't enabled CHECKPOINT_RESTORE in the kernel I was
testing. Add a decoding of errno to the testcase to make that obvious.
