[roll] Roll fuchsia Revert "[ffx][fastboot] consider boot timeout a success"

This reverts commit 021ad1fce51d7588f1ad02d21c03bcdec167d618.

Reason for revert: correlates with a sharp uptick in start_target_error across tasks using flashing to provision

Original change's description:
> [ffx][fastboot] consider boot timeout a success
>
> When issuing a "boot", "reboot", or "reboot-bootloader", it's
> possible that the "okay" response gets lost in a buffer. So
> inside of consdering a lack of an "okay" in those cases as a
> a timeout failure, consider them successes.
>
> Also, since we are now considering a timeout to be an expected
> result, let's timeout in only a few seconds instead of waiting
> 30 seconds.
>
> This change includes a fix to fastboot::read_with_timeout() to
> actually use a timeout, rather than blocking indefinitely
> and checking the timestamp after the fact.
