Disable the ORC unwinder. This feature requires libelf-dev, which is
breaking some automated build systems that do not have it installed.

As we already enabled CONFIG_FRAME_POINTER, we already incurred the
performance penalty of the legacy stack unwinder, so this is pretty
much a no-op change.

Bug: 63889157
