Do not propagate boot jars in CLC construction

Bootclasspath libraries are shared and available to apps by default.
Propagating the bootclasspath libraries in CLC and adding them in
manifest fixer may lead to discrepancies between the build time CLC and
the run time CLC, making dexpreopt usesless and leading to performance
regression.
