gotta-patch-em: Remove post_process

[why]
The previous change(s) removed executing the config.cfg **shell script**
which would pull in some environment variables like `post_process`.
With that change the appropriate option has to be given with the
commandline value of the new config.cfg **INI** file.

[how]
Remove defunct leftover code.
