pdftk: remove and replace with pdftk-java

- requires gcc6 libraries, which are now in /bootstrap
- replaced by pdftk-java:

> This is a port of pdftk into Java.
> The current goals are to keep functionality as compatible with the
> original as it is reasonable, to fix any issues present in the
> original (correctness takes precedence over compatibility, see the
> differences), and to clean up the code. New functionality may be added,
> but it is not a priority.

fixes #47176
