Add new ATF tests: kernel/t_zombie
New tests attempting to kill, stop, drop or revive a zombie: - signal1 (SIGKILL) - signal2 (SIGSTOP) - signal3 (SIGABRT) - signal4 (SIGHUP) - signal5 (SIGCONT)
New test race1 verifying whether there are any kernel races when processing signals to zombies, executing in a loop for 5 seconds.
These tests were inspired by a kernel unexpected behavior when a lookup of a dying process could result in two detected entities once as an alive process and once as a zombie.
race1 is similar to t_ptrace_wait* race1, however without ptrace(2) involved.
