lib/oe/package: Ensure strip breaks hardlinks
Normally, strip preserves hardlinks which in the case of the way our hardlink
rather than copy functionality works, is a disadvantage and leads to non-deterministic
builds. This adds a move into place after the strip operation to ensure hardlinks
are broken and we bring back build determinism.
