Fix flaky test in password-agent

The test_send_password_to_socket_EMSGSIZE function should not use a
hard-coded constant to trigger an EMSGSIZE error from send().

* dracut-module/password-agent.c (send_password_to_socket): Only save
  errno from send() if it returned < 0.  Show strerror(errno) if
  send() does return EMSGSIZE.  Show number of bytes sent if send()
  sends less than all bytes.
  (test_send_password_to_socket_EMSGSIZE): Do not skip this test on
  non-AMD64 platforms.  Try to find a suitable message size to trigger
  EMSGSIZE before testing send_password_to_socket(), and only skip
  this test if such a triggering message size is not found.
