xtables-translate: fix multiple spaces issue

This patch fixes a multiple spaces issue. The problem arises when a rule
set loaded through iptables-compat-restore is listed in nft.

Before this commit, two spaces were printed after every match
translation:

$ sudo iptables-save
*filter
:INPUT ACCEPT [0:0]
-A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p tcp -m multiport --dports 80:85 -m ttl --ttl-gt 5 -j ACCEPT
COMMIT

$ sudo iptables-compat-restore iptables-save

$ sudo nft list ruleset
table ip filter {
    chain INPUT {
        type filter hook input priority 0; policy accept;
        ct state related,established  counter packets 0 bytes 0 accept
                                    ^^
        ip protocol tcp tcp dport 80-85  ip ttl gt 5  counter packets 0 bytes 0 accept
                                       ^^           ^^
    }
}
