Add support for writing partition image in recovery images

This change updates the build system to account for dynamic GPT
partitioning on the device's internal disk when using recovery
images.

The `pack_recovery.sh` script requires the generated partition image
to correctly create a recovery image for devices that utilize
dynamic partitioning. This commit adds the necessary `--partition-image`
argument to the packing script invocation, passing the path to the
`gen-partition-image` output.
