Prevent misconfigured cp_system_other_odex=1 device boots

https://r.android.com/3177659 set ro.cp_system_other_odex=1 to request
copy of the dexpreopt app images to system_other partition on first
boot. This created a misconfiguration for devices that
1. Do not have a system_other partition
2. Do not have cppreopts.sh listed in PRODUCT_PACKAGES

This CL adds a conditional to request this copy operation in devices
with a system_other partition, and adds cppreopts.sh to PRODUCT_PACKAGES

Test: presubmits
