This is caused by arptables' postinst script:

+---
| if [ "$1" = "configure" ]; then
|    LIST="arptables arptables-save arptables-restore"
|
|    for i in $LIST; do
|        if [ ! -e "/sbin/$i" ]; then
|            ln -sf /usr/sbin/$i /sbin/$i
|        fi
|    done
| fi
+---

This intends to only create a /sbin/arptables -> /usr/sbin/arptables
symlink on non-usrmerged systems.

However, with arptables renamed to arptables-legacy, the condition `[ !
-e /sbin/arptables ]` is true on all systems and the /sbin/arptables ->
/usr/sbin/arptables symlink gets created on usrmerged systems as well.
And on these this is a /usr/sbin/arptables -> /usr/sbin/arptables
symlink.
