fix: invalid CLI use in scripts/{enable,disable}_log_statements.sh #546

- `find -name` => `find . -name`
- `xargs -i` => `xargs -I` (or can be replaced by the for loop)
- Use bash for loop instead of xargs to abort early when error happens
- Have one whitespace after `#` in the comments to conform with the
  standard python code style
