kitakami-common: Switch gps xtra servers to xtrapath{4, 5, 6}

 * Servers xtrapath1 and xtrapath3 are reporting the wrong week number
   (week rollover). Switch to servers xtrapath{4, 5, 6} as seen at
   https://developer.gemalto.com/threads/gps-time-info-error?page=1

 * I've verified the week numbers in the downloaded xtra data following
   this example https://docs.legato.io/17_10/c_gnssSampleCodeXtra.html
