PO can remove queens override again, bit by bit edition (#5143)

# About the pull request
PO can perform a 20 seconds do_after to remove additional 20 seconds of
the lockdown.

# Explain why it's good for the game
You used to be able to remove lockdown completely if you perform a 3
minutes do_after, but it was lost during the port to new shuttle system.
Now it's back in another, better form! Gives marines a chance to remove
lockdown sooner if they control the cockpit. In best case scenario you
can remove the lock in 5 minutes.
