thcrap: always dump patched files when patched_files_dump is true

Not overwriting the file when it already exists is a valid optimization only
when the file doesn't change. And patched files can change a lot more easily
than original files (usually, when I enable patched_files_dump, it's because
I want to see the result of a change).
