Futureproofs the nodrop check added in tgstation#80673 (tgstation#80722)

## About The Pull Request

See tgstation#80673 
I took a nap and got an idea how to make it better, so here we are

Less snowflake code, very robust, very good

Technically runs way more checks so it is slower but eh I believe it's
worth it in this case

Fully tested, it works as it should

## Changelog
:cl:
code: The check that prevents your stuff from dropping when you have
robotic parts is now more robust
