fix: two cases of NPCs printing messages in odd contexts

[chaosvolt]

Purpose of change

This fixes another couple of cases of NPC messages printing in cases where they shouldn't.

Describe the solution

1. In npcmove.cpp, set npc::move_to so the second case of having NPCs shout "lemme move ree" (the one that applies when the person blocking the way is a fellow NPC) doesn't trigger if the person committing Door Stuck is currently following the player. In this case it can be reasonably assumed they get the picture and will move out of the way on their own when the player does, and more importantly this fixes the constant "move plz" spam that happens when you've got more than one NPC follower tailing you.
2. In sounds.cpp, set sounds::process_sound_markers so you're only reminded about noise waking you up if the person being woke up is the player, not an NPC.

Describe alternatives you've considered

Making the sound message use a player-or-npc sorta message and having the NPC version be phrased as "the noise wakes up %s" or something like that.

Testing

1. Compiled and load-tested.
2. Recruited an NPC and forced them to be an eepy lil guy.
3. Set off firecrackers after waiting an hour into their snooze.
4. No message prints but sleeping status indicator goes away.
5. Set a laser turret on the other side of a wall plus a debug monster for it to shoot at.
6. Infected myself with the eepy, message still printed as expected when the lasers woke me up.
7. Recruited the poor bastard again and spawned an additional bunch of NPCs to follow along.
8. Followers get pissy when bumbling around the NPCs I failed to recruit but after a while of walking around don't seem to complain when bumbling over each other.
9. Checked affected files for astyle.
