We rely on the domain existing after xenstore-ls's main has called
exit, so that we can do our own xenstore-ls in dom0 and check the
results.
Previously, this happened by accident because the rump kernel would,
after _exit, call a minios function which crashes the domain. New
rump kernels don't do this, and instead shut down cleanly.
Setting `on_poweroff="preserve"' has the desired effect.
