fs_mgr: support AVB in fs_mgr_update_verity_state()

fs_mgr_update_verity_state() is invoked by 'verity_update_state' in
init.rc. It will then set property "partition.system.verified" and
"partition.vendor.verified" to verify_mode. We should support this for
AVB as well.

Also change the order of static libs in init to fix the build error
after this change:
  system/extras/ext4_utils/ext4_crypt.cpp:69: error: undefined reference to 'property_get'

Bug: 35416769
Test: Mount /system and /vendor with vboot 2.0 (AVB), check the following properties exist.
      - [partition.system.verified]: [2]
      - [partition.vendor.verified]: [2]
Test: Mount /system and /vendor with vboot 1.0, check the following properties exist.
      - [partition.system.verified]: [0]
      - [partition.vendor.verified]: [0]
