copy-builtin: SPL must be in Kbuild first (again)
Commit bced7e3 accidentally reintroduced issue #7595 which was
previously addressed by 517d247.  Re-apply the original fix to
resolve the issue and include a comment to make it clear the
ordering is important.

To compile this file system support as a module, choose M here.
If unsure, say N.
