Bug description:
  [Impact]

   * charon unnecessarily selects a wrong PSK in some cases:
     * A site-to-site connection using resolvable hostnames (e.g., DynDNS) as identities in /etc/ipsec.secrets and a Roadwarrior connection (using %any as remote peer identity)
     * Multiple site-to-site connections using resolvable hostnames as identities

   * Fix is a backport from upstream in since 5.5.2

  [Test Case]

   * There are detailed steps on how to configure for this case on 
     https://wiki.strongswan.org/issues/2223

  [Regression Potential]

   * It is known (see discussion in upstream bug) that this can slightly 
     increase the connection setup as it adds a dns query. But un-breaking 
     the covered use cases was considered worth to do so upstream, and so 
     should we.

   * By changing the IKEv1 PSK codepath is the only changed path, so this is 
     the area where unexpected regressions could occur. None of the testing 
     found some so far and since upstream didn't change it for a while it 
     seems safe to me.

  [Other Info]
   
    * n/a

  There is a chance to get an backport into xenial?
