Add missing "ImageURL" property to MountPoint interface

It fixes problem with missing information on VirtualMedia Redfish
resource after user mounts media using legacy method.
Part of VirtualMedia Redfish resource after fix:
{
  ...
  "ConnectedVia": "URI",
  "Id": "Slot_2",
  "Image": null,
  "ImageName": "smb://127.0.0.1/public/openSUSE-15.1-x86_64.iso",
  "Inserted": true,
  ...
}

Tested:
 - Mounted and ejected media using legacy method with success.
 - Received proper details about mounted image from Redfish.
