libpayload: Reduce media init timeout to 5 seconds.

Currently, we wait for up to 30 seconds for a device to become ready to
    respond to a TEST_UNIT_READY command. In practice, all media devices become
    ready much sooner. But, certain devices do not function with libpayload's
    USB driver, and always timeout. To provide a better user experience when
    booting with such devices, reduce the timeout to 5 seconds.
