Don't infer the default boot image location in otapreopt.

otapreopt calls derive_classpath but only takes BOOTCLASSPATH from the
output, not DEX2OATBOOTCLASSPATH or other env variables. The runtime
cannot handle this case when inferring the default boot image location
once aosp/2470962 is merged.

We don't have a boot image for otapreopt anyway, so just don't attempt
to infer the default boot image location.

Bug: 272573887
Test: ABTD (http://go/abtd-run/L42700000959054591): See no dex2oat
  crashes in the logs, though the test is failing due to another known
  issue (b/270940551)
