"shutdown -h now" should power off, but it just only the machine.

OpenRC mimics System V init system in this case, so System V init system interfaces documentation define how things must work.

According to shutdown(8) man page from sys-apps/sysvinit, `/sbin/shutdown -h ...` means "Equivalent to -P, unless -H is specified". And the option `-P` means "Action is to turn off the power". So acpid invokes a command which means powering off. So if openrc-provided shutdown tool doesn't power off the machine, it's the fault of openrc-provided shutdown tool.

The following statements have been confirmed.

* Commands "/sbin/shutdown -P now", "/lib/rc/bin/shutdown -P now" do turn off the power.
* Manually patching "h) shutdown_arg=--halt ;;" to "h) shutdown_arg=--poweroff ;;" in /lib/rc/bin/shutdown makes "shutdown -h now" to power machine off as expected.

Originally reported in https://bugs.gentoo.org/726092 .

Reproducible: Always

Steps to Reproduce:
1. install openrc[sysv-utils]
2. "shutdown -h now"
Actual Results:  
system halted

Expected Results:  
system powered off
