Server: Fix bug with --interface flag when "cc" is not installed.

* mandos (IPv6_TCPServer.server_bind): Since we fall back to setting
  SO_BINDTODEVICE to a hard-coded value if we failed to find out what
  it is, declare it as global so Python does not think that we are
  creating a new local variable.
