It appears that it is only possible to change each Emoji’s skin tone individually by tapping and holding on the Emoji key and selecting another skin tone in the pop-up menu.
Is it possible to set a default skin tone to be used across all the supported Emojis?
To switch to it on the keyboard, tap the globe icon between 123 and the microphone icon.
I'd say that's easier than downloading a third-party anything on Android. Plus it was included already 2 years ago with iOS 5.
You can try holding down on the emoji you want and see if it brings up a menu to pick the skin color like this:
That feature is mainly only available on the more "human" looking emojis. Doing this will now set the default of that emoji to the color you chose, so I guess you could go through all of them and pick the one you want and they should stay as the new default instead of having to pick from the yellow one every time, but there isn't a way to "revert back" to 8.2 and earlier styles.

No. Due to the way it is implemented, it is not possible to set a default skin tone to be used across all the supported Emojis in iOS Emoji keyboard.
Each Emoji remembers its last used skin tone. Also, the recently used section shows all the skin tones variations used for a single Emoji.
