Allow recovery-dtbo in recovery.img to be signed

Non-A/B devices need to include the DTBO image
within the recovery partition to be self-sufficient
and prevent OTA failures. The CL includes the size
of recovery DTBO in the size of the boot image to be
signed to prevent image truncation.

Test: Verified that recovery.img was not getting truncated.
