Documentation: dontdiff: Update with additional entries

Add a bunch of entries reflective of programs that the kernel build:
sortextable, dtc. And while at it, expand the lex*.c entries to cover e.g: dtc-lexer.c. Finally, exclude devicetable-offsets.h

Does anybody still use the dontdiff file? I wonder if we could automatically generate it from the .gitignore files... Oh well, meanwhile, I've applied this to the docs tree, thanks.
