Add AVB flags to compile recovery image
as a chained partition. This is required
for safe OTA when multislot support is
not present.

* AVB's `--flags 3` argument builds a disabled VBMeta with
disabled hashtree, so no need to set both flags individually.

Partitions that use vbmeta_system can be found by looking at
avb flag in fstab from boot ramdisk.
--flags 2 makes the verification function of avb always return a
positive result.
--set_hashtree_disabled_flag builds the vbmeta images with the
HASHTREE_DISABLED bit set and as a result they don't need to manually
disable dm-verity via e.g. 'adb disable-verity'.
The rest of the configuration is taken from

This can be checked by looking for a rild service in system.
If it's missing, then a vendor ril service is being used, in
our case, it is qcrild.

Partition sizes can be found by query-ing sysfs.
For example, for super partition.
> ls -la /dev/block/by-name/super
lrwxrwxrwx 1 root root 16 1970-03-23 06:51 super -> /dev/block/sda17
> cat /proc/partitions | grep sda17
259 1 8388608 sda17
The size needs to be multiplied by the block size used by
/proc/partitions, which is 1024 bytes.
Logical partitions found inside the physical super partition
can be found by looking for entries with the logical flag in the
fstab inside boot ramdisk.
