Remove some glaring false-positive patterns (#2300)

* Remove some glaring false-positive patterns

- `Yii` and `dpd` are common patterns due to javascript compressors
- Since `dpd` and `dpd.js` are the only way to detected Deployd,
  and deployd isn't a dependency of anything else, we should
  remove it, since it's too false-positive prone

This should close #2289

* Remove a leftover icon
