Fix build with 64 bits time_t

time element is deprecated on new input_event structure in kernel's
input.h [1]

This will avoid the following build failure:

hw/input/virtio-input-host.c: In function 'virtio_input_host_handle_status':
hw/input/virtio-input-host.c:198:28: error: 'struct input_event' has no member named 'time'
  198 |     if (gettimeofday(&evdev.time, NULL)) {
      |                            ^
