[nft PATCH] rule: fix printing of rule comments

[Arturo Borrero Gonzalez <aborrero@cica.es>]

From: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com>

Several fixes:
 * handles are printed last
 * simplify space games (an extra space was being printed)
 * comments are shown with `nft monitor' as well (missing before this patch)


Before this patch:

% nft list ruleset -a
[...]
chain test {
	iifname eth0 # handle 1 comment "test"

}
[...]

% nft list ruleset
[...]
chain test {
	iifname eth0  comment "test"
		    ^^
}
[...]

% nft monitor &
% nft add rule test test iifname eth0 comment "test"
add rule test test iifname eth0

After this patch:

% nft list ruleset -a
chain test {
	iifname eth0 comment "test" # handle 1
		    ^
}

% nft monitor -a &
% nft add rule test test iifname eth0 comment "test"
add rule test test iifname eth0 comment "test" # handle 1
