fs_mgr: set "partition.system.verified" when AVB is used in a A/B device
In a A/B device, system partition is mounted by kernel as root.
In vboot 1.0, the dm device name of system partition is "system" with
the following configuration in kernel command line:
- dm="system none ro,0 1 android-verity /dev/sda34"
In AVB, the dm device name is switched to vroot as:
- dm="1 vroot none ro 1,0 5201456 verity 1 ..."
When sending ioctl DM_TABLE_STATUS to query status, we should use "vroot" as the
dm device name for AVB. But still pass "system" for the callback function to set
property [partition.system.verified] instead of [partition.vroot.verified].
Bug: 36900078
Test: Use AVB to mount system in a A/B device, checks the property exists
[partition.system.verified]
Test: Use vboot 1.0 to mount system in a A/B device, checks the property exists
[partition.system.verified]
Test: Checks 'adb remount' will output warning message:
- dm_verity is enabled on the system and vendor partitions.
- Use "adb disable-verity" to disable verity.
