test rumpclient syscalls from a signal handler

Some tests for rumpclient fork.

h_reboot has been superceded by rump.halt

Add a simple and stress test cases for the rump remote syscall code.
Fun fact: since the server daemonizes into its own process group,
it's not in atf's pgrp. Use rump_sys_reboot() in atf cleanup to
kill the server after the test.

PR misc/54382: whenever open(2) is called with O_CREAT, make sure to
pass an open mode argument.

Limit test duration based on wall time instead of loops
(took a long time on slow platforms).

fix fallout from including signal.h in rump_syscallargs.h

Execute a variety of syscalls in the stress test, including opening
files and sockets.

Give the stress queen two modes: one which nicely suggests an exit
and another one which keeps moet et chandon in her pretty cabinet.

Establish signal handler already in parent. Otherwise the child
might be killed before it has a chance to run.

Print some more info in an attempt to try to understand why the
test fails in automated test runs but not my desktop.

Make sure stressclient worker threads complete their operation
instead of hanging.

Don't use printf in a signal handler.

XXX: it would be nice if the deadlock with malloc were a little
more obvious, especially since gdb doesn't provide any clues unless
you compile libpthread with -g
