Incorrect image url for arch.b4k.dev

[kaizerfreak]

Similar to #3512, #3408. arch.b4k.dev's image urls are in the format https://arch**-img**.b4k.dev/[board]/[filename] instead of https://arch.b4k.dev/[board]/full_image/[filename]

Replace these:

{ "uid": 25, "name": "not arch.b4k.co", "domain": "arch.b4k.dev", "http": true, "https": true, "software": "foolfuuka", "boards": [ "g", "mlp", "qb", "v", "vg", "vm", "vmg", "vp", "vrpg", "vst" ], "files": [ "qb", "v", "vg", "vm", "vmg", "vp", "vrpg", "vst" ], "search": [ "qb", "v", "vg", "vm", "vmg", "vp", "vrpg", "vst" ] },

and

file: function(archive, arg) {
      var boardID, filename;
      boardID = arg.boardID, filename = arg.filename;
      if (!filename) {
        return '';
      }
      if (boardID === 'f') {
        filename = encodeURIComponent($.unescape(decodeURIComponent(filename)));
      } else {
        if (/[sm]\.jpg$/.test(filename)) {
          return '';
        }
      }
      return "" + (Redirect.protocol(archive)) + archive.domain + "/" + boardID + "/full_image/" + filename;
    },

with

{ "uid": 25, "name": "not arch.b4k.co", "domain": "arch.b4k.dev", "media_domain": "arch-img.b4k.dev", "http": true, "https": true, "software": "foolfuuka", "boards": [ "g", "mlp", "qb", "v", "vg", "vm", "vmg", "vp", "vrpg", "vst" ], "files": [ "qb", "v", "vg", "vm", "vmg", "vp", "vrpg", "vst" ], "search": [ "qb", "v", "vg", "vm", "vmg", "vp", "vrpg", "vst" ] },

and

file: function(archive, arg) {
      var boardID, filename;
      boardID = arg.boardID, filename = arg.filename;
      if (!filename) {
        return '';
      }
      if (boardID === 'f') {
        filename = encodeURIComponent($.unescape(decodeURIComponent(filename)));
      } else {
        if (/[sm]\.jpg$/.test(filename)) {
          return '';
        }
      }
      return "" + (Redirect.protocol(archive)) + (archive.media_domain || archive.domain) + "/" + boardID + "/full_image/" + filename;
    },
