systemctl: honour inhibitors when shutting down or entering sleep state
build-sys: use _FORTIFY_SOURCE only if optimizing

Rather then force the user to undefine _FORTIFY_SOURCE,
don't define it in the first place if it cannot be used.

I'm assuming that -O* can only be sensibly specified in $CFLAGS.

systemctl: be smarter when mangling snapshot names

For "systemctl snapshot" it makes no sense to complete an incomplete
name with ".service" as we previously did, use ".snapshot" instead.
Also, don't bother with mount units or suchlike, we know that this must
be a snapshot and hence is the only sane way for completion.
