This is needed for the system images of aosp_arm(64) products to
be used as their respective GSIs in P, and for also aosp_arm(64)
products to boot with the current GSIs.
Bug: 78255604
Test: Built and booted the following products to home screen
$ lunch aosp_arm-userdebug; m -j; emulator
$ lunch aosp_arm64-userdebug; m -j; emulator
# The system image, both userdebug and user builds, of
# aosp_arm64 could also boot to home screen and browse
# the network on a physical device.
