Allow system server jars for WITH_DEXPREOPT_BOOT_IMG_AND_SYSTEM_SERVER_ONLY

Renamed WITH_DEXPREOPT_BOOT_IMG_ONLY to
WITH_DEXPREOPT_BOOT_IMG_AND_SYSTEM_SERVER_ONLY and changed the
behavior accordingly.

Preopt system server jars since selinux prevents system server from
loading anything from /data. If we don't do this they will need to
be extracted which is not favorable for RAM usage or performance.

Test: make and flash and look at system server maps
