Fix llamas not being controllable with '/npc controllable' (#2412)

Llamas are looped in with horses for certain traits (such as having an inventory) but not in movement. This commit excludes llamas from the `updateHorizontalSpeed` check as they cannot be controlled in vanilla.

Tested with 1.12.2 and 1.16.4.
