Asteroids use the wrong entrypoints

[Ikalpo]

Round ID:NULL

Testmerges:NONE

Reproduction:

enter a bunch of asteroids with a sabre, eventually you'll end up in an unloaded area. look at the asteroid's docking_points var and it will have multiple objs in the list at least one of the landmark/dropship_entry/ objs will be outside the asteroid, where the sabre ended up.

this is where the offending landmarks are added to the list https://github.com/BeeStation/NSV13/blob/c5c1151b711bf2e03a8991f3b1d1782f08377d53/nsv13/code/modules/overmap/boarding/interiors.dm#L155

A lot of this seems to happen on non-ferrous asteroids. I thought I entered some kind of weird-ass maze until I kept getting booted out

thanks for the detective work. game, why make landmark outside of template? why?
