[nft PATCH 1/3] src/rule.c: don't print trailing statement whitespace

[Arturo Borrero Gonzalez <arturo.borrero.glez@xxxxxxxxx>]

This trailing whitespace is annoying when working with the textual output
of nft.

Before:

table t {
	chain c {
		ct state new
			    ^
	}
}


After:

table t {
	chain c {
		ct state new
	}
}
