fix footstep sounds from being played while buckled (#42788)

Fixes the crawling sound from being played from moving buckled/mounted mobs.
## Why It's Good For The Game

Apparently I didn't catch the crawling sounds being played from buckled mobs that are moving. Examples include the Janitor on their pimpin' ride or some assistant piggy-backing off of a cyborg.
