functions-libvirt: Add log filter to capture CPU driver errors

Browse Source 
Two things:

  (a) Add the log filter to capture libvirt CPU manipulation driver
      related error messages when things fallout (e.g. CPU model
      comparision failures during live migration).

  (b) While we're at it, remove the "1:qemu_monitor" log filter, because
      the existing filter "1:qemu" should take care of logging the
      interactions with QEMU monitor console.  This is the case since
      the introduction of VIR_LOG_INIT() macro in upstream libvirt,
      which performs a substring match on a given file name.  (Available
      from libvirt version v1.2.10 onwards).
