Humanizing monkeys removes undergarments (tgstation#84439)

## About The Pull Request

Humanizing a monkey doesn't result in someone with trans thigh-highs and
a bra

## Why It's Good For The Game

It is kinda weird and bad for immersion. Humans can just get it back
from dressers anyways.

## Changelog
