Amend a patch that fixes compilation on non-Linux and non-BSD OSes.
There are several things that could be adjusted differently in the
function in question, but that needs to be discussed upstream. For now,
take the simplest route.
Also, be consistent with upstream's intent that "suspend" means ACPI
state 3, also being consistent with what was patched in xfce4-power-
manager before, too. (Where suspend and resume generally works for me
on NetBSD laptops, state 3 is effective.)
