Some device specific prebuilts have a suffix that varies depending on the lunch target. The resulting install dependency binary has the suffix. The fuzzer build expects the presubmit binary without the suffix. This change is to drop the suffix. Test: make haiku Change-Id: I8eadd84bf5797659b17bc428dca47b7c3f382aff
