shutdown: add a -q(uiet) flag to suppress warning messages

The system-wide warning makes sense in multi-user environments, but
shutdown(8) may be used on systems or in scenarios where there's nobody
to warn and wall(1) just introduces unnecessary complexity and overhead
to the shutdown process.

Add an option to suppress the warning entirely for those contexts that
want to do so, which are anticipated to mainly be in appliance or
single-user desktop-style systems.

Small tweak to the default behavior of shutdown -c

'shutdown -c' is supposed to power cycle the system rather than doing a normal
reboot. However, when that fails, it halts the system. This is not quite right
since the intent isn't to halt the system but to restart. Make the default init
behavior be to restart the system. The halt(8) interface can be used if you'd
like to powercycle or halt.

shutdown: Assume absolute time is in the future

The original bug describes it best:

When an absolute time is specified to shutdown, the program's
behavior depends on whether that time has passed during the
current calendar day. POLA would suggest that for shutdown,
whose time argument is always supposed to be in the future,
absolute times specified without a specific date should refer
to the next occurrence of that time, rather than erroring out
if that time has already passed during the current day.
