RFC tmpfiles: Allow configuration to ignore execution errors
This is an implementation that covers making errors encountered when writing
file content optionally fatal. If this is something that folks would want I'll
add handling of this for all the other directives. I'd appreciate suggestions
on how this might better be structured as well (use of a goto fail or such) as
I'm not super happy with the approach.
