update-xfonts-traditional: Generalise SIGPIPE handling in process_filter

If we didn't want to process this font, tolerate SIGPIPE for all
elements of the pipeline before "self", rather than special-casing
pcf2bdf.

(We end up setting {SigOK}{13} again for gunzip, which is fine.)

Now process_filter has no knowledge of particular pipeline stages.
