[topgen-fusesoc] Modify how the script handles output

The script previously outputed to a dedicated temporary directory
and deletes some files before generating them. Now that we are checking
files in, we need to change this behaviour. The script now doesn't
remote anything and outputs to hw/<top_name>.
