Liftoff code is never relocated and never serialized, thus relocation
information is not needed.

This results in slightly less information being printed when
disassembling code, because the disassembler sometimes uses relocation
information to show the kind of a call (e.g. internal wasm call vs.
builtin call). This is an acceptable regression IMO.
