tests: shell: cover transactions via nft -f using flat syntax

This patch covers transactions using the flat syntax representation, eg.

	add table x
	add chain x y { type filter hook forward priority 0; }
	add chain x y { policy drop; }

This also covers things like:

	add element x whitelist { 1.1.1.1 }
	delete element x whitelist { 1.1.1.1 }

The one above may look silly from a human behaviour point of view, but
silly robots may very well behave like this.

These tests require several kernel patches though in order to pass
successfully.
