fleet/ohm.yaml: fix arch/arm64 include path after merge rename

The merge commit renamed arch/arm64/xor-neon-ffixed-x18-scs-build-fix-danctnix/
to arch/arm64/scs-arm-neon-build-fix/ (= main's canonical name) but the
include reference in ohm.yaml didn't get updated atomically.

Update the include path to match the renamed dir; ka-promote would have
exit-2'd on this manifest otherwise.
