nft: don't use xzalloc()
In the current setup, nft (the frontend object) is using the xzalloc() function from libnftables, which does not makes sense, as this is typically an internal helper function. In order to don't use this public libnftables symbol (a later patch just removes it), let's use calloc() directly in the nft frontend.
