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.
