Removes flight from lavaland syndicate modsuits (#78649)

## About The Pull Request

Fixes #78557 
I wasn't really thinking of these guys when I gave nuke op suits the
ability to fly.
The lavaland syndicate base now simply spawns a modsuit with no jetpack
or jump jet in it.
Those guys aren't going to space, they don't need it.

## Changelog

🆑
fix: Lavaland syndicate operatives can no longer trivially use the
jetpack on their modsuit to fly over the lava.
