Disable AVB check in runtime vintf

GSI disables AVB by overriding vbmeta partition.
When a device can run runtime vintf checking, it should already
pass AVB, so we don't need to check AVB in runtime vintf.

We cannot change the original VintfObject.verify() because AVB check is
still needed for android.os.RecoverySystem to verify a newly downloaded
OTA package.

Bug: 68016134
Test: Boot with GSI and there is no Android System dialog
