Allow recovery to return error codes
Write error code, cause code, and retry count into last_install. So we
can have more information about the reason of a failed OTA.
Example of new last_install:
@/cache/recovery/block.map package name
0 install result
retry: 1 retry count (new)
error: 30 error code (new)
cause: 12 error cause (new)
