    wireguard-tools: fix script errors
    
    follow-up to 148207730a3c9f3aea807df336ca33792e9d3c0f
    
    Schoolboy error on the peer_psk value.
    
    Also fix an issue when joining peer IPv4 and IPv6 AllowedIPs
    (${peer_a_ips/ /, } replaces only the first space, while
    ${peer_a_ips// /, } replaces all the spaces).
