Well, it's indeed not a _pure_ bug fix, but given that O_TMPFILE is now
always defined, the guards are no longer needed at all: they will never
be guarding anything now.
Besides, using O_TMPFILE is way better than not using it; it makes the
thing a little bit more secure.

Damn. Upstream is not using SoB lines (Lennart asked me to remove them
[0] and I fiorgot to re-add them when adding them in Buildroot; the
previosu iteration did have my SoB lines).
