Log ioctl failures
Otherwise there is no way to determine why e.g. zzz(8) does not do anything
on certain machines; macppc and arm64 for example have no suspend/resume
suspend at all (for now) and loongson has partial support.
This still does not make `zzz' or `apm -z' report the informative
warning on standar error, but syslog now prints
apmd: system suspending
apmd: battery status: unknown. external power status: not known. estimated battery life 0%
apmd: suspend: Operation not supported
