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 introduce a new allocation function in the nft frontend.
This results in a bit of code duplication, but given the simplicity of the code,
I don't think it's a big deal.
Other possible approach would be to have xzalloc() become part of libnftables
public API, but that is a much worse scenario I think.
