groff: Fix determinism issue
Sometimes bison would regenerate source files and sometimes it would not This is likely related to the patching of generated files by on of the patches. Drop those changes and force the files to regenerate in all cases since we depend on bison-native anyway. This ensures the results are always consistent.
