objtool: Fix cross-build

Stephen Rothwell reported this cross-compilation build failure:

| In file included from orc_dump.c:19:0:
| orc.h:21:10: fatal error: asm/orc_types.h: No such file or directory
| ...

Caused by:

  6a77cff819ae ("objtool: Move synced files to their original relative locations")

Use the proper arch header files location, not the host-arch location.
