hiphi: Use RSA4096 key also for vbmeta_system

Browse source 
* Per https://android.googlesource.com/platform/external/avb/+/master/README.md#build-system-integration, SHA256_RSA4096 is used if BOARD_AVB_ALGORITHM isn't defined
* We can assume bootloader is able to understand a RSA4096 key for vbmeta_system as well
