kernel: Implement WEXITED for waitid.
Previously dead teams were always returned (as needed for wait/waitpid).
Using waitid it should however be possible to omit the WEXITED flag to
only get stopped (WUNTRACED | WSTOPPED) or continued (WCONTINUED) teams.
Adjust the other caller of the _kern_wait_for_child syscall, used by the
various less specific wait* functions, to always include WEXITED. This
avoids having to special case waitid in the syscall interface or with an
extra flag.
Add a check to ensure that any of these flags is set to avoid the now
possible case of nothing being specified. This fails with B_BAD_VALUE
(EINVAL) as on other systems.
