kamil ce34db38fd 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.

When adding new tests, please try to follow the following conventions.

1. For library routines, including system calls, the directory structure of
   the tests should follow the directory structure of the real source tree.
   For instance, interfaces available via the C library should follow:

	src/lib/libc/gen -> src/tests/lib/libc/gen
	src/lib/libc/sys -> src/tests/lib/libc/sys
	...

2. Equivalently, all tests for userland utilities should try to follow their
   location in the source tree. If this can not be satisfied, the tests for
   a utility should be located under the directory to which the utility is
   installed. Thus, a test for env(1) should go to src/tests/usr.bin/env.
   Likewise, a test for tcpdump(8) should be in src/tests/usr.sbin/tcpdump,
   even though the source code for the program is located under src/external.

3. Otherwise use your own discretion.
