This tests repeatedly creates and kills children, so some corner
cases in handling of not-quite-existing processes can be observed.
Previously, strace was crashing in the following situation:
13994 ????( <unfinished ...>
...
13994 <... ???? resumed>) = ?
as tcp->s_ent wasn't initialised on syscall entering and
strace.c:print_event_exit segfaulted when tried to access
tcp->s_ent->sys_name.
* tests/kill_child.c: New file.
* tests/kill_child.test: New test.
* tests/Makefile.am (check_PROGRAMS): Add kill_child.
(MISC_TESTS): Add kill_child.test.
