update_verifier: Support AVB.

When using AVB, PRODUCT_SUPPORTS_VERITY is not set so check for
BOARD_ENABLE_AVB as well. Also AVB sets up the root filesystem as
'vroot' so map that to 'system' since this is what is
expected. Managed to test at least that the code is at least compiled
in:

 $ fastboot --set-active=_a
 Setting current slot to 'a'...
 OKAY [  0.023s]
 finished. total time: 0.023s

 $ fastboot reboot
 rebooting...

 finished. total time: 0.050s

 $ adb wait-for-device

 $ adb logcat |grep update_verifier
