Replace PRODUCT_BOOT_JARS with DEXPREOPT_BOOT_JARS_MODULES for nopreloads

boot_profile_jars.zip is used to process the boot image profile (by
filtering out data that does not belong to the boot classpath).
We only need the jars that are actually preloaded, and not the ones which
are updatable.

Test: launch taimen_nopreload-userdebug; m
