Install /system/product_services apps odex in system-other.

This will cause odex/vdex files for apps installed under
/system/product_services/{priv-,}app to be installed in system-other
instead of next to the APKs themselves.

This change is analogous to I63406f91acc3de4b4f142767e28d45308706c7da,
which was for /system/product apps.

Test: diff installed-files{,-system-other}.txt on pixel with a PS app
