Bindat examples in source, not manual

* doc/lispref/processes.texi (Bindat Examples): Remove, fixing
a FIXME in the manual.  The long example had bitrotted to some
extent, compared to the more-up-to-date example in bindat.el
commentary, which apparently what people were referring to
anyway.  The short example was confusing and not that useful
and will be obsolescent anyway if we change timestamp format.
