objtool: Define 'struct orc_entry' only when needed
Implementation of ORC requires some definitions that are currently
provided by the target architecture headers. Do not depend on these
definitions when the orc subcommand is not implemented.
This avoid requiring arches with no orc implementation to provide dummy
orc definitions.
