Disable suspend when we're shutting down.  This solves the "tell FreeBSD
to shut down; close laptop lid" scenario which otherwise tended to end
with a laptop overheating or the battery dying.

The implementation uses a new sysctl, kern.suspend_blocked; init(8) sets
this while rc.suspend runs, and the ACPI sleep code ignores requests while
the sysctl is set.

Discussed on:	freebsd-acpi (35 emails)
MFC after:	1 week
