Fixes Marine Minor (Hive collapse)

[SabreML]

About the pull request

Fixes a runtime in /datum/game_mode/colonialmarines/check_queen_status() which was stopping the 'Marine Minor' round result (Hive collapse) from being set. (Added by a tiny mistake in #5442)

runtime error: type mismatch: cannot compare /list (/list) to 3
 - proc name: check queen status (/datum/game_mode/colonialmarines/check_queen_status)
 -   source file: code/game/gamemodes/colonialmarines/colonialmarines.dm,335
 -   usr: null
 -   src: Distress Signal (/datum/game_mode/colonialmarines)
 -   call stack:
 - Distress Signal (/datum/game_mode/colonialmarines): check queen status("xeno_hive_normal")

The totalXenos list itself was being compared to the number instead of the list's length, which aborted the proc before round_finished could be set.
I've gone through all of this year's game logs just to double check, and there hasn't been a 'Marine Minor Victory' since the 24th of January.

Explain why it's good for the game

Marines get a slightly worse victory condition again. (woo!)
