When test_send_signal_kern__open_and_load() fails parent closes the pipe which cases ASSERT_EQ(read(pipe_p2c...)) to fail, but child continues and enters infinite loop, while parent is stuck in wait(NULL). Fix the issue by killing the child before jumping to skel_open_load_failure. The bug was discovered while compiling all of selftests with -O1 instead of -O2 which caused progs/test_send_signal_kern.c to fail to load.
