Add dexpreopt option to build commands

Missed passing down the WITH_DEXPREOPT_BOOT_IMG_AND_SYSTEM_SERVER_ONLY
option in the build commands.

Test: ./build/make/ci/build_test_suites --target_product aosp_x86_64
--target_release trunk_staging --with_dexpreopt_boot_img_and_system_server_only --dist_dir <dist_dir> --change_info <change_info_file> <extra_targets>
