[MIRROR] Fixes some potential sleeps as detected by SpacemanDMM improvements (#1216)

* Fix some potential sleeps as detected by SpacemanDMM improvements (#54230)

overrides weren't detected by should not sleep, i think i've mostly
fixed that with SpaceManiac/SpacemanDMM#214

Some of these are wacky but overall this pr is harmless

signals shouldnt sleep even in weird 1 in a million situations or due
to other people adding bad code

overrides of changeling can_sting() use alert() and input() and that's
just too fucked for me to fix in this pr

* Fixes some potential sleeps as detected by SpacemanDMM improvements
