makepkg: fix $pkgname element duplication

run_split_packaging did not preserve the $pkgname array correctly, and
would create duplicate entries in the list during restore.

After restoring the backup (a b c) would become (a b c b c).

This probably went unnoticed because during --install, pacman would
reconcile the duplicates.
