X6833B: Build VBMeta image with --set_hashtree_disabled_flag

Browse source 
* This is equivalent to building with --flags 1, which just
  disables hashtree verification. This is enough for the bootloader
  to pass "androidboot.vbmeta.device_state=unlocked androidboot.veritymode=disabled"
  in the kernel command line, which is what we wanted this entire time.

* As explained in an earlier commit, any image with flags 3 will cause
  the bootloader to totally break, which is why we must use flags 1
  instead. Besides, flags 1 does exactly what we want it to now.

* PS: MediaTek fix your stupid bootloader
