Antag Scaling: Week 3 (#4032)

## Short description
Reduces antag scaling a little.

## Why we need to add this
To the relief of Security mains everywhere, after having played a few
hell shifts, I now realize how strained Security and Medical get when
gamemodes stack on top of each other.

Reverts my own -20% changes to antag scaling in
[#3502](#3502),
and also applies similar changes to Vampires and Changelings. (Roughly
10-20% slower scaling per common Antag.)

## Checks
- [X] I do not require assistance to complete the PR.
- [X] Before posting/requesting review of a PR, I have verified that the
changes work.
- [X] I have added screenshots/videos of the changes, or this PR does
not change in-game mechanics.
- [X] I affirm that my changes are licensed under the [MIT

**Changelog**
