[OE-core] update-alternatives: symlinks are not created

[Yevhen Kyriukha]

I've built custom image with busybox included and noticed that
symlinks for mkdir, ls, rm and other programs are not created.

In do_rootfs log I have the following error messages:
...
update-alternatives: error: alternative path /bin/busybox.suid doesn't exist
...
update-alternatives: error: alternative path /bin/busybox.nosuid doesn't exist
...
