Fix some new dreamchecker lints (#91844)

## About The Pull Request

https://github.com/SpaceManiac/SpacemanDMM/pull/435 added a new
dreamchecker lint, for SDMM `set` statements not at the top of the proc.

While this lint isn't in the current SDMM _release_, I was testing it
out earlier and saw these issues, so might as well fix them before they
even become an issue.

i also fixed a useless variable in moon heretic code that was right next
to the incorrectly placed `SIGNAL_HANDLER`

## Why It's Good For The Game
