[nft PATCH] expression: Fix inconsistent output in set

[Ana Rey <anarey@gmail.com>]

Add a whitespace between the last element in a set and the close braces.

Old output set:

	set set-test {
		type ipv4_address
		elements = { 192.168.1.44, 192.168.2.4}
	}

New output set:
	set set-test {
		type ipv4_address
		elements = { 192.168.1.44, 192.168.2.4 }
	}
