[Alexey Kopytov]

  Bug #1114955: xtrabackup_pid remains existed after execution

  Fix a regression introduced by the fix for bug #1055989: in case the
  xtrabackup process has finished copying the log file and terminated
  before wait_for_ibbackup_finish() is called, remove the stale
  xtrabackup_pid file.
