libcupsfilters: In pdftopdf() set a default for "print-scaling"

If no setting for "print-scaling" is provided via IPP attribute pr
command line option there is no default valur for it and we get
undefined behavior and also a scary "should never happen" message in
the log.

Now we check after parsing the appropriate IPP attributes and command
line options whether a setting was provided. If not, we use "auto".
