Prevent non-CA2_SPINDASH characters from getting crushed by roll-jumping into a crevice

Non-CA2_SPINDASH characters are much more likely to enter a rolljump state as of !1220 (merged), and thus also more likely to be subject to entering a crevice and being crushed upon touching the floor.

!1256 (merged) is helping to normalize spinning as an applicable mechanic for these characters, so I feel it's now appropriate to give them the same leeway that CA2_SPINDASH characters do when in this situation.
